Suppose I did not know their size, which is not the case in this example, so I've allocated arrays dynamically, and this is my example:



#include <stdio.h>
#include <complex.h>
#include...

anduril462, sorry I think I did not expressed myself in the right way. I can do these operations with other number types, and with things I read, now I saw that the allocation is the same.My question...

anduril462, your guess was wrong, my problens are with complex type.
Please, I would like to know how fill a complex arrary when the elements are in ohter array.

thanks

Please, I am beginner and I need to work with complex matrices in C, but do not know how to work with that type. I have an idea of how working with complex numbers, it would just declare a variable...

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

The code already complies before but gave problems when running, but now WORKED !!!!!

I changed two things:
when I was allocating the matrix was

Please, help me if you can.

When I printed the vector vetout I could see it.

So what should I do?

Sorry, this isn't the problem, in the original code p is defined like float *p, with *y and **A in the main, I just forgot to put here.

I'd allocated vetout in the begin of the function...
