I have this multi-import file, which ask user to importchose text and csv file. My text file columns information on the first row and I want to skip the first line. Any help would be much appreciated.
Sincerely
siva
clear
clc
[fileName,filePath] = uigetfile({'*.csv';'*.txt'},'Pick a file','MultiSelect','on'); %filePath is were the folder address is stored
if isnumeric(fileName); %fileName is were the file address stored
disp('Please pick multiple file');
return;
end
pathToFile = fullfile(filePath,fileName); % getting file name and folder name
x= size(pathToFile,2); % size of the pathToFile
disp('Stress and strain column in csv format are as follows: 8 & 7');
disp('Stress and strain column in txt format are as follows: 4 & 5');
prompt ='Please choose the Stress column from csv format';
stress_column_csv =input(prompt);
prompt ='Please choose the strain column from csv format';
strain_column_csv=input(prompt);
prompt ='Please choose the Stress column from txt format';
stress_column_txt=input(prompt);
prompt ='Please choose the strain column from txt format';
strain_column_txt=input(prompt);
for i=1:x
[pathstr, name, ext{i}] = fileparts(pathToFile{i}); %had to add this line to get the file extension
store = importdata(pathToFile{i});
if ext{i} == '.csv'
[val,idx] = max(store.data(:,strain_column_csv)); % finding the max value
c ={idx}; % idx contain cell value.
stress{i}=store.data(1:c{1},stress_column_csv);
strain{i} =store.data(1:c{1},strain_column_csv);
else if ext{i}=='.txt'
% [val,idx] = max(store(:,stress_column_txt));
% c ={idx};
stress{i}=store(:,stress_column_txt);
strain{i} =store(:,strain_column_txt);
end
end
end
title_name=input('Title? ','s')
cc=jet(x);
for i=1:x
figure(1)
plot(strain{i},stress{i});
hold on
legendInfo{i}=[fileName{i}];
end
legend(legendInfo)
xlabel('strain [%]');
ylabel('Stress [MPa]');
grid on;
title(title_name);

How are you reading in the text files? How are you reading in the csv files?

[pathstr, name, ext{i}] = fileparts(pathToFile{i}); %had to add this line to get the file extension
if strcmp(ext{i}, 'txt')
store = importdata(pathToFile{i}, ',', 1); %I am guessing about the delimiter
else
store = importdata(pathToFile{i});
end
