problem in MKL sparse BLAS for complex number

Hi,

I am problem using MKL Sparse BLAS functions for complex numbers. The strange thing is that I am able to use these functions, only for double type numbers. For example for the function mkl_?coomm, "mkl_dcoomm" works OK, but other variants e.g. "mkl_scoomm", "mkl_ccoomm" and "mkl_zcoomm" don't work and when I use these function the compiler shows "undefined identifier" for these functions. I have also overwritten MKL_Complex_16 with C++ complex data type and other functions work fine.

I have been able to use LAPACK functions for complex numbers without any problem (zgetrf+zgetrs) but not Sparse BLAS functions. I use Linux and Intel C++ compiler. Anybody can help?

Thanks in advance,

D.

Hi Dan,

I 'd recommend you to look at theMKLs Sparse BLAS Level 2 and 3 examples for matrices represented in all storage schemes.

You can find these examples into \examples\spblas\source\directory.

See, as an example, in cspblas_zcoo.c - look there how MKL_ZCOOMM routines has been called .

Hi Genady,

Yes I had seen these examples. The problem was in including the directory of MKL headers for C using "-I[path]". The function call was actually correct, but the problem was the function headers could not be found.
