ndarray-matrix-vector-product

Dense matrix-vector multiply for ndarrays.

Example

var mvp = require("ndarray-matrix-vector-product")
var zeros = require("zeros")

//Initialize some vectors and a matrix
var x = zeros([16])
var M = zeros([16, 8])
var y = zeros([8])

M.set(1,2,  10.0)
y.set(2, 3)

//Multiply y by M storing result in x
mvp(x, M, y)

Install

Install using npm:

npm install ndarray-matrix-vector-product

API

require("ndarray-matrix-vector-product")(out, M, y)

Multiplies a matrix by a vector

• out is an 1D ndarray with shape [n]
• M is a 2D ndarray with shape [n,m]
• v is a 1D ndarray with shape [m]
