mm_xpf: Dot Product SparseMatrix*DenseArray

Description

Dot product of simple triplet matrix x (m x n) (measurement matrix) and a dense array y (n x k x l). Only slices of y_ from lsel vector are used.

Usage

mm_xpf(x, y_, lsel)

Value

An array with dimensions (m x len(lsel) x k), i.e. it is permuted on the fly.

Arguments

x

A list, sparse matrix of type slam

y_

A numeric 3d array

lsel

An integer vector
