MatrixJs

MatrixJs is a small Javascript Library use to compute matrix

Usage

MatrixJs can do basic computing of matrix. such as - Finding Determinant, Transponse, Minor, Adjoint and more - Inversing

Tutorials

1. First We Import Matrix from MatrixJs

``js
import Matrix from "./MatrixJS";
`

2. To Create a Matrix we initate a Matrix class with 2 Dimenstional Array

`js
let MyMatrix = new Matrix([
[1, 2, 3],
[4, 5, 6],
[7, 8, 9],
]);
`

3. To access the matrix use

`js
console.log(MyMatrix.matrix);
`

$3

returns an array of [row, column]

`js
let size = MyMatrix.size();
let [row, column] = MyMatrix.size();

console.log(size); // [3, 3]
`

$3

`js
let determinant = MyMatrix.det();
`

or without creating a variable for the matrix

`js
let determinant = new Matrix([
[1, 2, 3],
[4, 5, 6],
[7, 8, 9],
]).det();
`

$3

`js
let inverse = MyMatrix.inverse();
`

or you can just change the matrix by passing true as a parameter

`js
MyMatrix.inverse(true);
`

$3

`js
let transposed = MyArray.transponse();
`

or to change the Matrix itself pass true parameter

`js
MyMatrix.transponse(true);
console.log(MyMatrix.matrix);

/*
[
[1, 4, 7],
[2, 5, 8],
[3, 6, 9]
]
*/
`

$3

Cofactor and Minor take two arguments row and column

`js
let cofactor = MyMatrix.cofactor(0, 1); // 6
let minor = MyMatrix.minor(0, 0); // -6
