nested for loop

[chenli868]

I have two array, one is 1d array named a[SIZE ],another is 2d array named b[ ][ ]. I want to find out the minimum difference in array a and store the value to array b. here is the c code:

for (i=0;i++;i<SIZE)

     for (j=0;j++;j<SIZE)

   b[ i ][ j ]= a[ i ] - a[ j ];

Could anybody tell me how to program this in LabView?

Thanks ~_~

Hi Chen,

      Attached are two VIs, "Diff.vi" implements your example exactly, it outputs the minimum value of the subtraction and the corresponding indexes.   

If you want to locate two values from A with the least difference between them, Diff_abs.VI is a little more efficient.

Cheers!

It is very useful. Thank you so much ^_^

A literal translation would be the following:

Hi chen,

      Your welcome! - but be warned: Diff.vi has a bug!

Diff_abs.vi is OK, but go with Altenbach's code if you really want the N by N array.

(I tested Diff_abs.vi then partially gutted-it to make Diff.vi which wasn't tested -)

Cheers!
