You should write a function that outputs A and B. function out = foo2(arg1, varargin) tempOut = foo3(varargin{:}); out = arg1 + tempOut; % Assuming I guarantee nargin >= 2 end The problem that I run … Script files cannot have the same name as a function in the file. This video shows the creation of a simple function, and then adding a subfunction to that original function. Functions and Sub Functions. alternatively, I also can save each sub-function as a separate .m file, and then invoke them in the main function. Learn more about function, subfunction MATLAB The name of the file must match the name of the first function in the file. So your main function will look like Then you can use the general subs command g=subs(f,old,new) which in our cases would be g=subs(f,x,c) or g=subs(f,x,x0). This six and a half minute video shows a function being created in MATLAB, then it shows a subfunction being added. separate functions or sub-functions . Learn more about symbolic toolbox, subs Functions must be at the end of the file. Example 1: Consider a function of the two Cartesian coordinates f(x, y) = 2xy/(x 2 + y 2) 2. But I run into the issue when I want to pass the variable list of arguments into a SUB-subfunction, for example.
