Mx - Matrices computing library

Reference

Core

Create new matrix

import Mx from 'mx-computing'
const matrix = new Mx.Matrix([
    [1, 2],
    [4, 3],
])

Get matrix cell

import Mx from 'mx-computing'
const matrix = new Mx.Matrix([
    [4, 1, 16],
    [2, 23, 3],
])
matrix.cell(2, 0) // returns 1

Get matrix row and rows number

import Mx from 'mx-computing'
const matrix = new Mx.Matrix([
    [51, 22],
    [44, 36],
])
matrix.row(0) // returns [51, 22]
matrix.rowNum() // returns 2

Get matrix column and columns number

import Mx from 'mx-computing'
const matrix = new Mx.Matrix([
    [4, 12],
    [7, 8],
])
matrix.column(1) // returns [12, 8]
matrix.colNum() // return 2

Transpose matrix

import Mx from 'mx-computing'
const matrix = new Mx.Matrix([
    [4, 7],
    [8, 6],
])
const transposedMatrix = matrix.transpose()

Math

Merge pair of matrices

import Mx from 'mx-computing'
const firstMatrix = new Mx.Matrix([
    [4, 12],
    [7, 8],
])
const secondMatrix = new Mx.Matrix([
    [14, 7],
    [86, 5],
])
const mergedMatrix = Mx.MMath.mergePairOfMatrices(firstMatrix, secondMatrix)

Subtract pair of matrices

import Mx from 'mx-computing'
const firstMatrix = new Mx.Matrix([
    [7, 4],
    [2, 77],
])
const secondMatrix = new Mx.Matrix([
    [7, 47],
    [22, 4],
])
const subtractedMatrix = Mx.MMath.subtractPairOfMatrices(firstMatrix, secondMatrix)

Multiply pair of matrices

import Mx from 'mx-computing'
const firstMatrix = new Mx.Matrix([
    [6, 5],
    [3, 1],
])
const secondMatrix = new Mx.Matrix([
    [6, 7],
    [9, 2],
])
const multipliedMatrix = Mx.MMath.multiplyPairOfMatrices(firstMatrix, secondMatrix)

Act pair of matrices

import Mx from 'mx-computing'
const firstMatrix = new Mx.Matrix([
    [6, 5],
    [3, 1],
])
const secondMatrix = new Mx.Matrix([
    [6, 7],
    [9, 2],
])
const actedx.MMath.actPairOfMatrices(firstMatrix, secondMatrixm (valueA, valueB) => valueA + valueB - 2)

Available Scripts

In the project directory, you can run:

yarn

Install required dependencies

yarn start

Open http://localhost:3000 with auto-refresh

yarn lib

Built library final versions that will be placed in /lib directory

Bash scripts

In the proroject directory /scripts, you can ron following bash scripts:

test-and-build.sh

Test and build library by yarn test and yarn build automatically.

publish.sh

Publish library to npm registry. *Note that you are not albe to run that script because you are not equipped with npm auth token. That is just additional informaiton
