Like the subject. Anyone know about it?

Right, there is no exact function to do this.

MKL lapack provide one function ?lakf2

Forms a matrix containing Kronecker products
between the given matrices.

Include Files
• mkl.h
Description
The routine ?lakf2forms the 2*m*nby 2*m*nmatrix Z.

You may check if it can work. Otherwise, you may call

for loop mxn

mkl_?omatcopy (aij * B)
Performs scaling and out-place transposition/copying
of matrices.

do Kron(A,B)
