Here is a problem which I am entangled with: http://stackoverflow.com/questions/22288888/multiplying-transposed-matrix-with-jblas

Then any tips to optimize this? Thanks.

Yeah, BLAS supports multiplying in place, but I never exposed this to jblas. But one could have a custom function for multiplications of the form A^T B or AB^T
