mathjs/lib/function/construction/matrix.js

Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, big numbers, complex numbers, units, and matrices.

module.exports = function (math) {
  var util = require('../../util/index'),
      Matrix = require('../../type/Matrix');

  /**
   * Create a matrix. The function creates a new math.type.Matrix object.
   *
   * The method accepts the following arguments:
   *     matrix()       creates an empty matrix
   *     matrix(data)   creates a matrix with initial data.
   *
   * Example usage:
   *     var m = matrix([[1, 2], [3, 4]);
   *     m.size();                        // [2, 2]
   *     m.resize([3, 2], 5);
   *     m.valueOf();                     // [[1, 2], [3, 4], [5, 5]]
   *     m.get([1, 0])                    // 3
   *
   * @param {Array | Matrix} [data]    A multi dimensional array
   * @return {Matrix} matrix
