Using an array as an output

I have a function and the output must be a one-dimensional array consisting of the elements y1, y2, y3, and y4.

Do I have to make a subfunction or nested function in order to define the output?

Simply writing

output=[y1 y2 y3 y4]

does not work.

"Simply writing [...] does not work". If "the elements y1, y2, y3, and y4" are scalars I cannot see why it shouldn't work.

It said that the variable is undefined. Maybe this is because it is an output?

I would need to see all the code to be sure. Did you try seperating the elements with a coma, and was output the return falue of the function?
