how to call a function one m-file to another m-file

lets say i have one m-file named call1.m having:

function t =call1(a,b)
a=10;
b=5;
t=a+b;
end
and i want to call and run this function 't' in another m-file named call2.m, i wrote it as:

function call2()
t = @call1
end
but nothing happens please guide me.
Thanks

You only need the ‘@’ operator (creating a function handle) if you are using the function as an input argument to another function. You are not here, so do this instead:

function call2()
t = call1
end

Star Strider's suggestion will work because of the way your call1 function is written. The line that declares call1 tells MATLAB that it accepts up to 2 input arguments. Star Strider's code calls it with 0, and that works, because call1 completely ignores what you pass into it and overwrites those variables with hard-coded data.

If you eliminate the lines in call1 that assign values to a and b, then you could do this using a slightly modified version of Star Strider's code:

 function call2()
 t = call1(10, 5)
 end

If you want to DO anything with that result, though, you probably want to define call2 in such a way that it returns the variable t to its caller.

 function t = call2()
 t = call1(10, 5);
 end
