LinearAlgebraUtils

public static class LinearAlgebraUtils.BMulTask
extends FrameTask<LinearAlgebraUtils.BMulTask>

Computes B = XY where X is n by k and Y is k by p, saving result in new vecs Input: dinfo = X (large frame) with dinfo._adaptedFrame passed to doAll yt = Y' = transpose of Y (small matrix) Output: XY (large frame) is n by p
