I want to create a matrix using a little program with Kronecker Delta (1 if i=j, 0 if not) however it does not work.

Commands

Where is the mistake?

Thanks!

Kronecker delta is a function in Mathcad/Prime, so it needs to be called with parameters 'delta(i,j)' rather than with indices 'delta[i,j'.

I can't open your sheet (unrar produces an error message), but I should guess that Prime's error message is that delta is undefined...?

Success!

Hi,

You do not need to increase "j" it happens automatically,

You have return statement for D in the first for loop not outside it.

Ok, but the Kronecker delta is well used?

Hi,

The return of D needs to be outside of the for loops

You can use identity matrix for Kronecker Delta

Please attach your worksheet to clarify your problem.

You may have to zip it first. A serious bug in this forum often prevents from attaching a mathcad file. In Windows Explorer click with the right-mouse button on the mathcad file and select 'Send to' -> 'Compressed (zipped) folder'. The resulting .zip file can be attached
