+   * Compute the maximum value of a matrix or a  list with values.
+   * In case of a multidimensional array, the maximum of the flattened array
+   * will be calculated. When `dim` is provided, the maximum over the selected
+   * dimension will be calculated. Parameter `dim` is zero-based.
+   *
+   * Syntax:
+   *
+   *     math.max(a, b, c, ...)
+   *     math.max(A)
+   *     math.max(A, dimension)
+   *
+   * Examples:
+   *
+   *     math.max(2, 1, 4, 3)                  // returns 4
+   *     math.max([2, 1, 4, 3])                // returns 4
+   *
+   *     // maximum over a specified dimension (zero-based)
+   *     math.max([[2, 5], [4, 3], [1, 7]], 0) // returns [4, 7]
+   *     math.max([[2, 5], [4, 3], [1, 7]], 1) // returns [5, 4, 7]
+   *
+   *     math.max(2.7, 7.1, -4.5, 2.0, 4.1)    // returns 7.1
+   *     math.min(2.7, 7.1, -4.5, 2.0, 4.1)    // returns -4.5
+   *

+   *    mean, median, min, prod, std, sum, variance
+   *
+   * @param {... *} args  A single matrix or or multiple scalar values
