How to read text file in object oriented programming ?

Hello, I would like to know how can I read a text or an excel file in the object oriented programming ? I have a simple code like this.

|

classdef diego

        properties
            column 
            sampleRate = 1000
        end
      methods

          function y = readtext(this)
               fileID = fopen(this);
               C = textscan(fileID,'%f %f %f %f %f %f %f');
               fclose(fileID);
               disp([num2str(this.file),' is the chosen column is',num2str(this.file)]);
               disp(['The chosen column of the text file is ',num2str(this.column)]);
               y = C;
           end
       end    
  end

As you can see, I would like to read a text with readtext method. How can I overcome with this problem? Thanks

The problem is that this, the first input to your function readtext, is the object not the text file. If you want to pass the text file name in, make it the second input:

d = diego
readtext(d,'file.txt')

And then you readtext signature should be:

function y = readtext(this,filename)
   % this is object, filename is file name.
   fid = fopen(filename);
   % etc
