Enclosing class:

LinearAlgebraUtils

public static class LinearAlgebraUtils.BMulInPlaceTask
extends water.MRTask<LinearAlgebraUtils.BMulInPlaceTask>

Computes B = XY where X is n by k and Y is k by p, saving result in same frame Input: [X,B] (large frame) passed to doAll, where we write to B yt = Y' = transpose of Y (small matrix) ncolX = number of columns in X
