Accessing variables via .mat files?

    I have 15 `.m` files which are script files and containing code at least 500 lines each (say `file1.m`, `file2.m`, `file3.m`, `file4.m`, `file5.m`, `file6.m`, `file7.m`, `file8.m`, `file9.m`, `file10.m`, `file11.m`, `file12.m`, `file13.m`, `file14.m`, `file15.m`) and one `Main.m` file which is also a script file.

    I want to access all files (all variables of these files) in `Main.m` and plot all variables in `Main.m` file, so that all the variables come to Matlab Workspace.  
    I already tried `file1` via function method and `.mat` file method but not succeeded yet and `Main.m` gave error 

    > undefined variable

    in `Main.m` file I write `save file1.mat` and `load file1.mat` and also tried it via function but still error.  
    Can any one tell me via code example how can I do it via `.mat` file method? I observed that `Main.m` when run `load` only one m file variables and not all to workspace.the Main.m code is below

    Mainfile.m
    %clear all
    % close all
    % clc
    tic

    please observe in the Main.m code i have m files Gadeferrable.m,Ganondeferrable.m and so on which are 15 m files which are script files and i want to use,add etc all variables of these m files in Main.m file and want to make all plots in main.m accessing values of variables from all these m files

Answer 1

[Explorer]

you can just write name of m-file in command window and m-file will execute.

Let's say the names of files are file1.m, file2.m, ...

Write this in command window:

file1
file2
