Options

Math.js contains a number of configuration options. Options can be set when creating a math.js instance.

• matrix.defaultType. The default type of matrix output for functions. Available values are: "array" or "matrix" (default). Where possible, the type of matrix output from functions is determined from the function input: An array as input will return an Array, a Matrix as input will return a Matrix. In case of no matrix as input, the type of output is determined by the option options.matrix.defaultType. In case of mixed matrix inputs, a matrix will be returned always.
• number.defaultType. The default type of numbers. Available values are: "number" (default) or "bignumber". Big numbers have higher precision than the default numbers of JavaScript.

Example usage:

// load the library
var mathjs = require('mathjs');

// create an instance of math.js with default configuration
var math1 = mathjs();

// range will output a matrix
math1.range(0, 4); // Matrix [0, 1, 2, 3]

// create an instance of math.js with configuration options
var options = {
  matrix: {
    defaultType: 'array'
  }
};
var math2 = mathjs(options);

// range will output an Array
math2.range(0, 4); // Array [0, 1, 2, 3]
