Using MatLab:

Given the following function, which statement is true?

function [m,s] = stat(x) n = length(x); m = sum(x)/n; s = sqrt(sum((x-m).^2/n)); end 

Question 2 options:

A:	This function requires two formal parameters
B:	n,m,s can be accessed outside of the function. For example, in the Command line
C:	the 'end' at the end of the function can be omitted
D:	This function has no return value
