I have used a matlab file named arena.m.. In this file i have used many variables(orientation,centroid...). i have called for 3 matlab files blue.m,yellow.m,black.m from main file arena.m,,,, can u suggest a way to pass arguments to files blue, yellow , black and get back the changed values correctly... is ther anyway to do it without arguments??
 

Hi,

Standard matlab calls are by value (not by reference).
But you can get the modified values as ouputs, for instance you can call the "blue" function like this:

newValueBlue = blue( oldValueBlue );

and the same for the other functions.
Obviously, blue.m must return the new value as output.

i am using a function which should pass all the values to other function. how can i do that??
 

remember you can return multiple results from a Matlab function, e.g. say you have a file swap.m
Code: 
function [a, b] = swap(a_in, b_in)
a = b_in;
b = a_in;
end
you can use it so
Code: 
x=5
y=10
[x,y]=swap(x,y)
