If I have a function f1 defined in a f1.m file and another f2 in f2.m, how to use these two functions in another function definition f3 in f3.m? And How do I use variables created/ used in the f1 and f2 files, in the f3 function?

Hi Sushanth,
When the functions f1 and F2 are in the path where function f3 can acess, then you can directly use the functions name to access the function.
For example,
function out = f3(in1,in2) a = f1(in1); % call th function signature end As shown above the usage with f1, even F2 can be called within the function f3.
The scope variables within a function are only present till the execution is within the function. Thus, you cannot acces intermediate variables of f1 and f2 in f3. In case it is required to use them, pass them as outputs to the respective functions.
For more details about functions, look at topics in the page here .
Hope this helps. Regards, Sriram

Easy save all the functions in same folder and run.
function val = TwoSum(a,b)
val = a+b;
end
function val = ThreeSum(a,b,c)
val = a+b+c ;
end
function out = Check(a,b,c)
sum1 = TwoSum(a,b) ;
sum2 = ThreeSum(a,b,c) ;
out = sum1+sum2 ;
end
