Hello, Maple wizards.

I have a problem with Tasks for parallel computations. In each task my programm should execute this command:

>B:=SignalProcessing:-DFT(A)

"A" and "B" are Arrays (1..m). "m" is integer. I have 8 tasks. Each task is a loop ("for i from 1 to n do..." n is integer), where my command is executing. "A" and "B" are local for each task. In this case each task should execute my command n times.

So, I obtain this:

"Error, (in SignalProcessing:-Engine:-DFT) attempting to assign to `FwdDFT` which is protected"

What is it? In Maple Help I read that ">SignalProcessing:-DFT" is Thread-Safe Function.
