Help with Function

Please,does anyone knows a function in free libraries to compute a matrix which every terms are:

e^(-iBC)


where:

-i means complex
B and C are terms that I know



Thanks!

And you can't code a couple of lines of math on your own?

Take a look at GSL though I am not very sure it is what you need.
Btw if you are using c99, it supports complex numbers.

That's what I meant... unless the OP is using some ancient compiler, the necessary tools should be part of its libraries...

He needs to start coding...
Then, as usual, if he gets stuck he can post his code and we'll see what we can do...
