function out = foo2(arg1, varargin) tempOut = foo3(varargin{:}); out = arg1 + tempOut; % Assuming I guarantee nargin >= 2 end The problem that I run … So your main function will look like Based on the question it seems "Scores" is a N*3 matrix (N shows number of students). 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). Learn more about functions, subfunctions, homework You should write a function that outputs A and B. The name of the file must match the name of the first function in the file. problem with subs function . Usually, I keep the function and the sub-functions in one .m file. Example 1: Consider a function of the two Cartesian coordinates f(x, y) = 2xy/(x 2 + y 2) 2. Functions must be at the end of the file. But I run into the issue when I want to pass the variable list of arguments into a SUB-subfunction, for example. Learn more about symbolic toolbox, subs alternatively, I also can save each sub-function as a separate .m file, and then invoke them in the main function. Here old, new can be arrays. Learn more about function, subfunction MATLAB Functions and Sub Functions. Ask Question Asked 3 years, 9 months ago. The result g is still a symbolic variable or symbolic constant in “Maple”. Functions are supported in scripts in R2016b or later. Viewed 554 times 0. Is there any way to define a variable in main function and use it in all sub-function. Functions are a way of adding to the MATLAB language. There are several types of functions used in MATLAB. This six and a half minute video shows a function being created in MATLAB, then it shows a subfunction being added. my question is what the difference between this two way. Script files cannot have the same name as a function in the file. separate functions or sub-functions . Active 3 years, 8 months ago. It is required when any function in the file contains a nested function or function used is a local function within the script and function file. subs(s) returns a copy of s, replacing symbolic variables in s, with their values obtained from the calling function and the MATLAB ® Workspace, and then evaluates s.Variables with no assigned values remain as variables. In a script file which contains commands and function definitions. This video shows the creation of a simple function, and then adding a subfunction to that original function.
