Hello,

I can't seem to find the solution for my problem. I created a function which gives 4 outputs. I call the function in the command window:

x = rand([50,1])
a([1,2,3,4])= descriptives(b)

descriptives gives the max,min,mean and std for a random vector. I want to store these 4 values into a vector, but I don't know how to do it...

Thanks

Try this:

[a(1),a(2),a(3),a(4)] = descriptives(b)

This assumes ‘descriptives’ returns 4 separate scalar values.

More robust with preallocation:

a = zeros(1,4);
[a(1),a(2),a(3),a(4)] = descriptives(b)
