how to use result of one function for another function??

i want to use the results of one function for another function within the same or different file...plese help me how to do it....

sample program:

function [ y ] = heatsource( x1, x2 )
function [ x1, x2] = result( c, d )
c=2;
d=3;
x1=c+d;
x2=c-d;
end

y=x1+x2;
y
end

mainscript.m

c=2; d=3;
[ x1, x2] = result( c, d ) 
[ y ] = heatsource( x1, x2 )

result.m

   function [ x1, x2] = result( c, d )
   x1=c+d; 
   x2=c-d;

heatsource.m

   function [ y ] = heatsource( x1, x2 )  
    y=x1+x2;

thanks for giving time to my problem and providing suitable solution... i want to know that is that method possible if i write the algorithm in diffrenet script files in form of functions.......then will it work if i call all the fuctions(5 functions created) in a seprate script file.

for example.....create result.m and hetasource.m in different script files. and call them in mainscript.m

exactly.

Should result.m and heatsource.m be in the same folder so heatsource.m can read x1 and x2?

[Andrei Bobrov]

function [ y ] = heatsource( c,d )
    function [ x1, x2] = result( c, d )
        x1=c+d;
        x2=c-d;
    end
    [ x1, x2] = result( c, d );
    y=x1+x2;
end

Save this function as heatsource.m

function [ y ] = heatsource( c,d )
[ x1, x2] = result( c, d )
y=x1+x2
function [ x1, x2] = result( c, d )
x1=c+d;
x2=c-d;

Then in Matlab windows command call your function with c and d argument

c=2;
d=3;
y=heatsource(c,d)
