I'm calling LAPACK/BLAS from C++ and was wondering what the complex16* type is in C++. I guess it is a built in type of Fortran, which consists of two Real-8 types.
From various examples on the web, it seems like it is just a double type or twice the size:
complex16* = double with double=real part, double=imaginary part. I have all
the other routines working because a double is obviously just a double in C++.
For example, the function zdotu_(int *N, complex16* X, int *incx, complex16* Y, int *incy),
[which takes the dot product of time complex numbers]
is supposed to return a type 'Complex16*', which I guess is a type in Fortran.
Does anybody know what this type is in C++? Is it a structure with 2 double pointers
with names 're' and 'im' or is it just a double. From here, I would really like to know how to store the value of zdotu_. Do you write something like:
