Element-wise Matrix Multiplication

I'm new to IPP and am trying to find the function (if it exists) that supports element-wise matrix multiplication. I've found some matrix operations, but none of them seem to support element-wise operations. Can someone please point me in the right direction?

Thanks!

Good question Sergey, I should have been more explicit.

Using Matlab notation:

[a1,a2 ; a3,a4] .* [b1,b2 ; b3,b4] = [a1*b1,a2*b2 ; a3*b3,a4*b4]

Thanks!

two comments on this topic:

1) all -- ipp mxm operations are well optimized for very small matrixes ( <= 6x6)

2) in the case if need to compute larger problems, I would recommend you to look at MKL's implementaion of m x m operations.
