     * Create a unit. Depending on the passed arguments, the function
     * will create and return a new math.Unit object.
     * When a matrix is provided, all elements will be converted to units.
     *
     * Syntax:
     *
     *     math.unit(unit : string)
     *     math.unit(value : number, unit : string)
     *
     * Examples:
     *
     *    const a = math.unit(5, 'cm')    // returns Unit 50 mm
     *    const b = math.unit('23 kg')    // returns Unit 23 kg
     *    a.to('m')                       // returns Unit 0.05 m
     *

     *
     *    bignumber, boolean, complex, index, matrix, number, string, createUnit
     *
     * @param {* | Array | Matrix} args   A number and unit.
     * @return {Unit | Array | Matrix}    The created unit
