Matrix of cross product on a HP 50 g

I'm doing a cross product of a vector.

-30k

0.1I + 0,173j

When I have this entry in the matrix and then drive choose the vector product out VECTOR - CROSS menu, I get "cross error: bad Argument Type.

What I am doing wrong?  I tried to go through the manual and it is not much help.

Thank you!

Hello

Enter it in quotation marks simple (MTRW button), that is:

'-30 * k'

Also note that when you enter the vectors in the matrix writer, don't forget to check the VEC selection:

(Notepad next to VEC)

Otherwise the calculator will interpret it as a matrix, even if there is only a single line (you will see thick material so thin instead).

It is a matrix:

and it is a vector:

  • OpenGL Helper Library (GLU)

    Hello

    There no GLU library in the ndk blackberry?

  • the upgrade card mother DM3-Pavilion

    Hello

    My 4 year Pavilion dm3, recently died on me. It's a little elegant machine, I wanted to wear around and who was always OK for occasional daily tasks. For these reasons and others, I would at least try to replace the defective motherboard and revive.

    The model I bought is a dm3-1003tx exotic model (bought in Thailand, especially with a keyboard QWERTY/thai), with Intel SU7300 and discrete nVidia GeForce G 105 M graphics chip.

    Given that the original motherboard is not easy to find (PN 584079-001, only a couple of bids on ebay of the Japan), can someone tell me:

    -If it's OK to replace it with an another based SU7300 of motherboard (can be with or without the nvidia chip - I really don't need it).

    -or even better upgrade to a motherboard of SP9300 based to get a performance gain? If so, should I expect any change (it looks that the consumption of energy and the frequency of the buses are higher with the SP9300 then maybe RAM...?)

    Is there any tool available around compatible HP part numbers?

    Thank you

    No, there is not a matrix of cross, useful reference because it would be. I think that HP is simply too many different models and parts for someone to keep track of it all. HP Service is inspired by replacement with the same part number so their internal service people wouldn't even have much use for such a thing, just us end users.

    Motherboards have the processor soldered to the and there is only a single part number for the fan/radiator Intel stated so I would say that if you replace your motherboard with it:

    580663 001

    with the SP9300, you'll be able to reuse your fan/radiator. In the case where you don't have it here is the repair:

    Manual

    All models use the DDR2-800 memory and accept up to 8 GB. Different motherboards all seem to have the same ports and such and will have the same anchor points. You could even theoretically install a card mother AMD-based, but this would require to reinstall an operating system, and I wouldn't trade an Intel processor for an AMD processor in any case unless AMD have been much cheaper. A Committee from AMD would also require a different radiator, however.

    You can buy the SP9300 motherboard for $45 shipped on eBay:

    The same seller also has the SU7300 for a few dollars less:

    I bought a little of this seller and it looks like they have a lot of them on the spot so must have dismantled a certain dm3s. Maybe if you call them they can steer you in a way or another based on real practical experience. I confess that I have the opportunity to work on this exact model.

  • Interaction term in MLG

    Hello

    I was wondering if there was a way to include an interaction term between two predictors When you create a regression model of GLM (be it with DBMS_DATA_MINING or GUI DataMiner) ?

    With R, I would use a similar to the following call: lm (y ~ r * s, data = d).

    Thank you!

    In fact, I have several predictors but only 2 of them specifically be an interaction term. »

    Yes. You have a few options on what kind of combinations are made. You will also need to turn on component selection if you have generation feature on.  Use the ODMr UI to get the best understanding of what options are integrated.

  • Non-unique Jobticket.xml ID names after the initial transaction, what gives?

    Hi all

    We had a problem where the names of IDS Jobticket.xml created for each transaction are not unique beyond the first transaction after the restart of IDS.

    ID 12.2 using 2.5 / SO with DM 12.2 in an environment and 12.3 2.6/SO with 12.3 SE DM in another and train to perform double printing output for each transaction (e.g. RECIPIENTAFP and RECIPIENTPDF).

    We can see that the first transaction cross product double output (afp and pdf), and file names are correctly named our IDSRequestObject, including a name unique jobticket.xml.

    However, successive transactions simply increment the previous name of jobticket.xml with _0001, _0002, etc., and the names of output files are not updated accordingly.

    Could you tell if there is a setting in the fsisys/fsiuser, something in the IDSRequestObject or maybe a native config to code Docupresentment, so the names of reset/refresh/create a unique jobticket.xml for each transaction?

    We are using MQ and moving to JMS eventually, but which should probably not have an impact on the creation of names from jobticket to Docupresentment.

    While hoping that there is a simple answer we can have overlooked in our dev environment.

    Thank you!

    No worries of friends.

    Now, everything's fine.

    Thank you.

  • How to create views of data from different databases tables in2

    Using Oracle 10.2 g

    I have 2 databases Gus and the haggis on schema Comqdhb.

    Glink indicates a link of database between Haggis and Gus

    In Gus, there is school that contains columns with same name upn, grade, subject, student of tables...

    STUDENT
    UPN
    academicYear

    Object

    Object

    GRADE
    examlevel
    grade

    SCHOOL
    SN

    In HAGGIS raising tables, grade, teacher containing columns upn... desc below.

    STUDENT
    UPN

    GRADE
    grade
    UPN
    academicyear
    level



    Create views in your database HAGGIS who join their all the qualities of the review. You should have a point of view that will produce the following relationship:
    examGrade (upn, subject, examlevel, sn, rank, academicYear)

    So I need to create a view that gets the data from the tables in the databases.

    create view as examGrade (upn, subject, examlevel, sn, rank, academicYear) like some s.upn


    But I don't get the selection of a column of 2 tables in different databases

    I mean if I said

    Select the UPN in comqdhb.student@glink,comqdhb.student;
    Select the upn name in comqdhb.student@glink,comqdhb.student
    *
    ERROR on line 1:
    ORA-00918: column ambiguously defined

    Help me, thank you.

    Hello

    Rider wrote:
    The issue is that I can't understand that I should create the view by the union of the haggis and the two gus data or only haggis.
    the reason I believe I need to combine the two is mentioned * "" create views in your database schema HAGGIS who join their all the qualities of the review. ". *
    By the mention of creating views and who join their all the qualities of the review, it probably means to obtain the data of the GUS and HAGGIS.

    This is my interpretation of the assignment, too.
    If you ask just the tables on Gus, you will get the ranks of three of the four schools: it's not all examination classes.
    If you ask just the tables on Haggis, you will get the ranks of any of the four schools: it's not all examination classes.

    2nd prob is that if have decided to create a view that gets the data from these two gus and therer haggis would be a lot of duplication involved due to the cross product

    Why would there be "repetition involved due to the cross-product"?
    If the quuery of Gus produces 100 lines, the request of product Haggis 30 rows, then the UNION of the two will have 100 + 30 = 130 lines (assuming, as you say, each student is at school only one).

    the query I wrote is

    Create view examGrade (upn, subject, examlevel, sn, rank, academicYear)
    as
    Select distinct s.upn as upn, g.subject as topic,
    g."LEVEL" as examlevel, g.grade as rank, to_number (g.academicyear) as academicyear
    of s comqdhb.student, comqdhb.grade g
    s.UPN, sb.subject, g.elevel, g.grade, s.acyr select Union
    of comqdhb.subject@glink sb,comqdhb.student@glink s,comqdhb.gradevalues@glink g;

    You should not write, not to mention not formatted zip code. I have a little time I can devote to answering questions in the forum. Do you want me
    b spend this time formatting your code, so I can understand the question, and no time to answer, or
    b spend only a little time reading understanding your code and spend most of my time to help you?
    I would prefer (b), but the choice is yours.
    See the statement that I posted in my last post for an example of the formatted code. You see how it appears in a box with a police fixed-width, and multiple spaces are printed? This is because I typed {code} (all small letters), before and after the section I wanted formatted.

    At least put each table in the FROM clause on a separate line, so it is easy to know if you have enough join conditions.
    If you have N tables in the FROM clause, you almost always have at least N-1 join conditions that specify how the tables are linked together. For example, if talk you about two tables, quality and student, you expect to see a join condition that tells you when you have data in a table, how to find related data in the other table, such as

    g_gus.upn = s_gus.upn
    

    No no no join conditions will cause "repetition involved due to the cross product.

    I downloaded my info here

    http://www.upload4free.com/download.php?file=184648736-ExamGrades_Case_Study_2008FINAL.PDF

    Sorry, if there is data as long as you can't post here, there is much too much for me to read.
    Make a sample set, containing a few (maybe five) students and a few shades of each student. It is fine to copy a few lines of your actual data.

    That's all the time I have for today. I can't wait to get the data and formatted requests.

    ORA-32044: cycle detected while executing recursive WITH query
    Any idea?
    Correct me if I'm wrong, but I remember, oracle supports as many JOIN CROSSROADS notation for Cartesian product (vector product =). For example
    SQL> WITH tmptab1 AS
      2  (
      3      SELECT 'a1' AS colval FROM DUAL UNION ALL
      4      SELECT 'a2' AS colval FROM DUAL UNION ALL
      5      SELECT 'a3' AS colval FROM DUAL
      6  ),
      7  tmptab2 AS
      8  (
      9      SELECT 'b1' AS colval FROM DUAL UNION ALL
     10      SELECT 'b2' AS colval FROM DUAL

    So if the two rated commas and CROSS JOIN have the same semantics, why do I get a cycle mentioned above cites recursive subquery factoring while the same query works pretty well with comma between table instead of CROSS JOIN names? Because if a cycle is detected (= current element ancestor) it means that the product with the CROSS JOIN notation produces duplicates which are absent in the result of the Cartesian product rated comma.

    I would appreciate it if you could kindly shed some light.

    Thanks in advance,

    Kind regards

    There is no doubt that a Cartesian product (also called cross join) is a join. If loops in a WITH recursive clause are detected after completing the joins, but before other conditions apply, the relevant question here is "what are the requirements to join?
    In the ANSI syntax, the distinction is always clear. Join conditions occur in the... Clause WE

    SELECT  employee_id, manager_id, lvl + 1
    FROM      employees
    JOIN        tmptab          ON  (manager_id = empId)     -- Join condition
    ;
    

    and other conditions occur in the WHERE (or HAVING or CONNECT BY) clause.

    SELECT  employee_id, manager_id, lvl + 1
    FROM            employees
    CROSS JOIN         tmptab
    WHERE  (manager_id = empId)     -- NOT a join condition
    ;
    

    In the joins of the former, it seems to be the case that any condition involving 2 or more tables (or the + indicator of outer join) is a condtion of join:

    SELECT  employee_id, manager_id, lvl + 1
    FROM      employees
    ,         tmptab
    WHERE  (manager_id = empId)     -- Join condition
    ;
