Options

Math.js contains a number of global options. The options are defined in math.options.

• 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 math.matrix.defaultType. In case of mixed matrix inputs, a matrix will be returned always.

Example usage:

var math = require('mathjs');

// default setting
math.ones(2, 2); // Matrix "[[1, 1], [1, 1]]"

// change default matrix output to array
math.options.matrix.defaultType = 'array'
math.ones(2, 2); // Array "[[1, 1], [1, 1]]"
