a_b_oneR Documentation

Compute a right-multiplication with the ones matrix

Description

Compute a * (b %*% one_mat) where a, b, ones_mat are square matrices of the same size, and ones_mat contains all entries equal to one. The product * is an entry-wise (Hadamard) product, while %*% represents matrix multiplication. This method is more efficient than the naive approach when a or b are sparse.

Usage

a_b_one(a, b)

Arguments

a, b

Square matrices.

Value

The square matrix a * (b %*% one_mat).
