Very basic IDL vector question [message #93147] Mon, 02 May 2016 23:24

I am trying to understand the operation of an IDL program. There are several lines using vectors which I do not understand.

The first line is:

fc = call_function(fun,xc)

Here, xc is a vector.

Is fc a scalar or vector, being that xc is a vector?
If fc is a scalar, which element of xc is being used for the function calculation?
If fc is a vector, does that mean that the vector fc is filled with all the function evaluations of the x values in xc?

Thanks for any assistance.
