Quick way to find the number of terms not zero in a matrix or an image

I try to use the standard deviation PtbyPt Vi.  It takes a series of points, can be reset when you start the calculation.  There is also an entry for the sample size.  I am calculating some statistics on a table... and would only include as items not null in the sample.

Is there a quick way to look at a picture and find many items not anywhere?

Thank you.

Hi Hummer,

test the table for "unequal to 0", convert the table of Boolean resulting in numbers and summary table. Just three primitives of LabView.

Do not forget:

-for large bays you need an additional step of conversion before summing up the table of numbers I32

-for big tables, this can lead to 'out of memory' problems due to the creation of copies of data
