Sqrt of matrix

[Amer7]

@StephenG1CMZ
This works when In CAS

It works but I have to know the size of the Matrix.

The issue with my programs is when I get an assignment I never hav the same MatrixDimensions. There are a lot of calculations between the Matrices, that's why I have to write these programs.

How can I call CAS in normal program. Like if I have:

Code:

Begin
Local Nn3,Mm3;
Nn3:=M1+M2;

Now do I write?
#CAS
begin
Mm3:=SQRT(diag(Nn3));
END;
EDITMAT(Mm3,"SQRT values of diagonal elements of Matrix Nn3");
END;
