Answer 1

[ES]

Do you need this?

file/program 1: name it as calling_function.m

 function calling_function()
  n=45;
   sqre_out=called_function(n)
  if sqre_out > 10
  ...
  ...
  end

file/program 2: name it as called_function.m

function out_no=called_function(in_no)
out_no=in_no*in_no;

did not get this...would u please explain it again?

[ES]

1. have an m file by name calling_function.m
2. Define the function calling_function() in that file
3. have another m file by name called_function.m
4. Define the function called_function(in_no) in that file
5. You can call called_function(in_no) from calling_function.m**

**better both the files(programs) be in the same directory. Or atleast add the path of the called file to matlab path by using addpath command. Otherwise MATLAB will not know where to look for the called file/program..
