Hi,

I would like to know rough number of single precision floating point operations (SP FLOP) of Intel MKL lapack cheevx function for a 48-by-48 complex matrix. Where can I find this information?

Hi Rajitha,

Unfortunately, We couldn't share the internal implementation of Intel MKL. However, you could refer to a reference book “Matrix Computations” by Golub and Van Loan for your reference on the algorithms.
