Making a Function with output only, no input

Need to start by hardcoding the test data into two 1D arrays. X's are 1, 2, and 3 and y's are 4, 5, and 8. The input parameters to the function will be void (that is, no input) and the output will be the two arrays defined in the function. Once you program works, I can then substitute the experimental data. Therefore, I want the size of the pre-allocated arrays to be as large as the largest set of data I expect to have.

Matlab allocates on assignment...the arrays will be whatever size you create them as. There's really no point in a function here at all...just put the data into a file and read it. But, the form of the function would be

function [x,y]=returnxy()
  x=[...];  % your data here
  y=[...];  % your data here
end

So this is what I did before even and I only get the one array output.

Run / call the function by typing as below in the command window.

[x,y] = getData() ;
