  /**
   * 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, valuelessUnit : Unit)
   *     math.unit(value : number, valuelessUnit : string)
   *
   * Examples:
   *
   *    const kph = math.unit('km/h')   // returns Unit km/h (valueless)
   *    const v = math.unit(25, kph)    // returns Unit 25 km/h
   *    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
   *
   * See also:
   *
   *    bignumber, boolean, complex, index, matrix, number, string, createUnit
   *
   * @param {* | Array | Matrix} args   A number and unit.
   * @return {Unit | Array | Matrix}    The created unit
