* Calculate the size of a matrix or scalar.

|
|
* Syntax:
|
|
*
|
|
* math.size(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.size(2.3) // returns []
|
|
* math.size('hello world') // returns [11]
|
|
*
|
|
* const A = [[1, 2, 3], [4, 5, 6]]
|
|
* math.size(A) // returns [2, 3]
|
|
* math.size(math.range(1,6)) // returns [5]
|
