Writing function that ether gives as a result or that uses a two-dimensional array as input?

Hello.

I have been trying for hours to get a function to work as for example

 function [data] = failure(value, somethingElse)

where data is a 2x2048 double array, or value being a 2x2048 double array. I don't need both to be 2x2048 but I fail to make any function using such a variable, does any one know how a function using that kind of variables would look like?

Regards

This is not clear. We don't know what your function has to do

It is very easy to use arrays in Matlab. Just open a new file "myfun.m", define a function

 function y = myfun(x)
 y = 2*y;

save the file and call it from the command line or from some other function. e.g.,

R = ones(2, 2048);
R2 = myfun(R);
