Re: #define issues

Well yeah....
the code looks like that. it's not exactly what i typed in....it does the calculating of the rows and columns just fine. It's actually making the assignment. 'value' is a double and the elements in matrix are doubles. But i keep getting 'incompatible types in assignments'...

(and it seems like the error is in "matrix[whatever] = value" for some reason)
i cant seem to figure if it's a syntax error or what ? how would you set a value in a #define ?

Cheers,
Aaron.
