Hi,
I would appreciate a lot if someone could give a hint in
how to solve the following problem. In the example I give
below I succeded to compile the program till I got the
expression ["a= sum(A(Range(0, 5))*A(Range(10,15)));"] and
put it in a function then I couldn't compile any more my
example.
Am I forgetting anything?
Thanks in advance for any help.
Carlos Silva.
