How do write a function within the same main code

Hello everybody,

I want to know if it is possible to write a function within the same main code rather than write it in separate M file.

Thanks in advance for any help.

Put all of this into one M-file. Then call it like this: get_sub(5)

function [OUT] = get_sub(A)
OUT = subfun(A);  % Call the subfunction.
function [OUT_SUB] = subfun(B)
OUT_SUB = B.^2;
