Is there a readfile() function in Matlab?

I'm going through an old research assistant's matlab code that was supposed to process files for raw data, plot the found data, and then save the figures as images.

In their code they use a function called readfile()

 A=readfile(FinalM);
        n_start=0;n_end=-1;
        for n=1:numel(A)
            if strcmpi(A{n},'[data]'),n_start=n+1;end
            if n_start>0 && n>=n_start && ~any(A{n}(1)=='-0123456789')
                n_end=n-1;break
            end
        end

From what I can tell (because they didn't document their work....) Matlab does not have a built in function readfile(), so I assume this is a function someone created and is available online

Can someone let me know if readfile() is a thing and/or if there is a function that would work better at opening a text file, scanning each line to find where the data starts, and then importing the data found into a 2 column matrix (x & y data)

Thanks for any help you can give. I am a lowly undergraduate just embarking on their journey with MATLAB, so I apologize in advance

Perhaps they meant this third-party function:

To get a copy either click the big blue "Download from GitHub" button or you could use the install add-ons feature of the MATLAB IDE:

Ahhh I believe you're right. Thank you!
