How to insert code segments from another MATLAB file?

Hello!

Could anyone tell me how can I "import" MATLAB code segments into another code?

I mean, I have some parameters in a file and I want to embed it in a function, for example, a data input.

input.dat:

x=1;
y=2; % or something more complex than that

main code:

function result = func(M)
    % I want to insert my input here
    M=M*x;
    result = M+y;
end

Thanks for your help!

Are you sure you want to do that? I cannot justify this construct.

Rename input.dat to my_input.m, move it to a folder that's in the search path and add the line

my_input

to your function.

There usually are 3 ways that I have seen people do this.

• in your func.m add a comment with a special TAG (e.g. %#mycode), then replace the TAG with the code you want. This can be done with simple fileread(filename). This will work for *.m or any other text files
• in your func.m call a script as per is suggesting (this could be empty or with data) so your func.m will always run, it may error out if the script file is not generated properly
• in your func.m if you are only loading variables you could always load a mat file

Hope this helps
