MathWorks does not warrant, **and disclaims all liability for,** the accuracy, suitability, or fitness for purpose of the translation. If A is a 0-by-0 empty array, then std(A) returns NaN. This feature is useful for networks with multi-element outputs.

- The difference is that a mean divides by the number of elements.
- If dim = 2, then std(A,0,2) returns a column vector containing the standard deviation of the elements in each row.
