How does a function have multiple return values in Julia (versus MATLAB)?

Question

In MATLAB, the following code returns m

and s

:

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

If I run the commands

values = [12.7, 45.4, 98.9, 26.6, 53.1];
[ave,stdev] = stat(values)

I get the following results:

ave = 47.3400
stdev = 29.4124

How can I define my function stat

in Julia?

For more information, see the Multiple Return Values section in the Julia documentation:

Julia returns a tuple of values to simulate returning multiple values. [...]
