* Elements of Arrays and Matrices are processed element wise.

* Syntax:

* math.string(value)

* Examples:

* math.string(4.2); // returns string '4.2'

* math.string(math.complex(3, 2); // returns string '3 + 2i'

* var u = math.unit(5, 'km');

* math.string(u.to('m')); // returns string '5000 m'

* math.string([true, false]); // returns ['true', 'false']

* See also:

* bignumber, boolean, complex, index, matrix, number, unit

* @param {* | Array | Matrix | null} [value] A value to convert to a string

* @return {string | Array | Matrix} The created string
