As I know, Blas is written in FORTRAN and in Fortran there is complex type. But for zher2k in C, I have to use complex number as an argument. I found there is a "complex.h" in C99. But I tried it and it doesn't work.
So I want to use CBlas. There are two functions called cblas_her2k and cblas_syr2k. For the places I use complex number, I have to pass a number as void* type to the function. So how can I use it? Are there any examples for these complex numbers in C?
Many thanks and appreciate.
