/**
|
|
* Compute the sum of a matrix or a list with values.
|
|
* In case of a (multi dimensional) array or matrix, the sum of all
|
|
* elements will be calculated.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.sum(a, b, c, ...)
|
|
* math.sum(A)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.sum(2, 1, 4, 3) // returns 10
|
|
* math.sum([2, 1, 4, 3]) // returns 10
|
|
* math.sum([[2, 5], [4, 3], [1, 7]]) // returns 22
|
|
*
|
|
* See also:
|
|
*
|
|
* mean, median, min, max, prod, std, variance, cumsum
|
|
*
|
|
* @param {... *} args A single matrix or or multiple scalar values
|
|
* @return {*} The sum of all values
