Zeta Matrix

Introduction

This is a simple matrix library including the following functions:

1. Addition
2. Subtraction
3. Multiplication
4. Entrywise multiplication

How to use

//Create a matrix object
var matrix = new Matrix([number of row], [number of col]);

//Add value to the matrix
matrix.write(1).write(2).write(3);

//Add all values to the matrix
matrix.writeAll(
    1, 2, 3,
    4, 5, 6,
    7, 8, 9
);
matrix.print(); //Print the matrix

4                 5                 6                 
7                 8                 9      

//Transpose
var matrixT = matrix.transpose(); //matrix will not changed.

//Matrix

//Addition (add) / Subtraction (subtract) / Multiplication (multiply)
//Parameter [Const / Matrix]
matrix.add(3).print(); //Note that the matrix will be updated.

var newMatrix = matrix.clone();
