How do I read one element from a 2D array

[Andy Blue]

Hi. I have a series of images, each saved as a 2d array in txt files . 

They have 525x525 elements.

Currently i have written a sub-vi that integrates all of the numbers for 2D array

However, now i would like to read the value of

a)1 element from each 2d array

b) And  in the future, a sub-set of elements (eg 10x10 array starting at (250,300)

I have up to 400 arrays at a a time. Any suggestions? Thanks

Andy

The "Index Array" function under "Arrays" on the diagram palettes allows you to supply both row and column indices, returning a single element (using only one or the other returns a whole row or column) and the and "Array subset" can be used to extract subportions of a larger 2D array.

P.M.
