Problem with textscan for importng textfile
显示 更早的评论
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.

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
