Do you mean something like this?

Yes,but the problem that mathcad gove me error becuase it can't recognize matB when adding to mat c

Did you run the attached worksheet?  I've just run it again for various values of matrix size and it seems to work on my M15.

I notice that in your original post, you give the variable names as MatA, MatB & MatC, whereas you mention matB & matC above - Mathcad variable names are case sensitive, so you need to ensure that all variables are spelled consistently.  You also need to have defined all of the variables before you can use them.

I did more simple code on Mathcad.can you please check it?

The code looks basically all right (apart from not returning the matrix SO), but you need to define the SO matrix before you can use it.

I'm not sure how this code makes any sense.

But it works if all three matrices already exist.

CAN YOU PLEASE SEE THIS CODE?@

I guess you were already told what the problems with your sheet are:

1) You have not defined the Matrix PO. You use elements of that matrix in your sums, so Mathcad has to know whoch values it should add.

What you are doing is like defining

L:=25

and then trying to calculate

PO := PO + L

Mathcad tries to evaluate the right hand side and does not know the value of PO. So it has to throw an error.

2) Your routine does not return the Matrix PO as a result. So kl would just be the result of the last addition.
