Hi

I`m trying to make simple calculation but without success. What`s the problem?

MC15 file is attached for convenience.

Thanks in advance.

Or use this alternative definition of it:

(The symbolic processor is not so fond of programming constructs, it likes pure mathematical expressions better.)

 

Success!

I get this in Mathcad 11.

(The error messages are the same for all red evaluations).

Apparently it's not 'simple'.

 

Success!

Problem is in delta function, if you change it by 1 for example everything is OK.

If you change double sum by two summing loops inside program block everything is OK too!See attached file

Thats exactly the very same problem as you had here

Seems like the symbolic doesn't like strings

I just gave it a try in Prime 6 and the new symbolic (while in many cases weaker and less capable even compared to muPAD) does not have this problem:
