How to call/include/load one m file in another m file?

Asked by Micky

I have a huge matlab program (.m file) which is a higher level model of some design and this program has bunch of variables. I want to store these variables in different/separate matlab file which should be .m file. So, I want in this way because I want to make changes with the variable values and run the original matlab program, basically run experiments with the model with new variable values. I know we can store varibles in mat file but it is not writable. So, basically my question comes down to this, I can store varibales in a separate m file but everytime I run the original program, how can I include and load the variables (m file) in the original matlab program file (m file)?

To run a .m file in another, just call the name of the .m file. For example, if you have two files A.m and B.m, to call B within A just type:

B;  %this will run B.m

There are many more or less smelly alternatives, one of which is a "data class". Example:

    classdef    MyInput
        properties ( Constant = true )
           p01 = 17; 
        end
    end

refer to the data in your huge program with

    >> MyInput.p01
    ans =
        17

This approach helps make your code a bit more readable.

"... make changes with the variable values ..." - how many variable?
