Matrix

This package provides a class with basic matrix manipulations

Install

npm i @thomas-inst/matrix --save

Usage

import {Matrix} from '/your/installation/path/Matrix.js'

Create a matrix

let m = new Matrix(20, 10, -1)
// m contains a matrix of 20 rows x 10 columns 
// with each element initialized to -1

Note:

• Elements can have anything as their values (string, int, object, ...)
• Rows and columns are numbered starting from 0

Get / Set any value

let v12 = m.getValue(1,2)
// vl12 ==> -1

m.setValue(1,2, 123)
// m.getValue(1,2)  ===> 123

Log the matrix to the console

m.logMatrix()

Compare it to other matrix

let m2 = new Matrix(20, 10, '-')
m.isEqualTo(m2)
// ===> false

Get rows and columns

let r1 = m.getRow(1)
let c1 = m.getColumn(1)

Add and delete columns

m.addColumnAfter(1, -2) 
// m now has 11 columns, with column 2 containing the value -2

m.deleteColumn(2) 
// m has 10 columns again

Clone it!

let m3 = m.clone()
