Problem with textscan for importng textfile

Hi, i many text files named Data. I attached as exemple one file to schow the structure of it. I wrote a function to read the Data of these files.

 function [All]=myfunction(numoffiles)
    for k=1:numoffiles
      fid=fopen(['Data_' num2str(k)  '.txt']);
     if fid == -1, error('Cannot open file'),
     end       
      XX{k,1}=textscan(fid,'%f %f %f');
      fclose(fid)
      Amplitude{k,1}=XX{k,1}{1};
      Resonance{k,1}=XX{k,1}{2};
      Height{k,1}=XX{k,1}{3};
      end
  All.Amplitude=vertcat( Amplitude{:});
 All.Resonance=vertcat(Resonance{:});
 All.Height=vertcat(Height{:});
 end

when i run this function with matlab 2014, i does what it should. But with Matlab 2017 i get Pronblems. Could someone help to solve the matter. mybe there is an easier way to sove it.

Please explain the problems with details. Perhaps the files are not found or anything else happens. While you know already, what the problem is, we cannot even guess it without using a crystal ball.

dlmread might be a better choice for reading this file.

I only had one file so I used a loop to read it twice to test the code.

This works in R2017a:

All.Amplitude = [];
All.Resonance = [];
All.Height = [];
for k1 = 1:2
    fidi = fopen('Rica Data_2.txt','rt');
    XXc = textscan(fidi, '%f%f%f', 'CollectOutput',1);
    fclose(fidi);
    XX = cell2mat(XXc);
    Amplitude = XX(:,1);
    Resonance = XX(:,2);
    Height = XX(:,3);
    All.Amplitude = [All.Amplitude; Amplitude];
    All.Resonance = [All.Resonance; Resonance];
    All.Height = [All.Height; Height];
end

Thank you for you answer. That is what am looking for. it does function with the data_2.txt which i attached. But when i use it for the real Data_2(large data) it does not work as i expect. I attached the Data_2.txt. thank you
