Hello,
I would like to know how you can use a function in another function.
e.g // function [ gam, alfa, beta] = att(L) should make use of the funciton s2abcd.m
abcd=s2abcd(data,50);
A= abcd(1,1,:);
I need to use that A matrix in another m file gam= cosh(A)/L; alfa=real(gam);
In C++ it can be done easily with include function but I dont know how you can do that in Matlab
Thanks in advance

Your comment to Luffy's answer shows, that your problem does not concern the access of the function at all. Therefore I strongly recommen to follow the standard procedure:
  1. Post the relevant code by copy&paste, such that even typos are replicated. Pseudo-code in the forum reduces the chance to find the error.
  2. Copy the complete error message including the line, which causes the error.

Just make sure the m-files in which both function & subfunction are in same directory.

Actually both of them are in the same directory but still I get the following error message
***Undefined function or variable "abcd".
Error in att (line 4)
A= abcd(1,1,:); ***

As long as the other M-function is stored in a folder, which belongs to the Matlab PATH, or in the current folder (see cd command), you can calling the function works by using its name - as expected.
For adding a user-defined folder to the path type pathtool to the command window, or open the corresponding menu.
