Hi , I wonder whether there is a separation function for conducting the matrix-vector multiplication directly like prodvec or cross-product function,
https://privefl.github.io/bigsnpr/reference/bed_cprodVec.html.

It looks like such multiplication has been implemented in the function snpgdsPCA for calculating PC. I just find no exported function for this basic operation. It should be faster than seqApply, right?
