Creating Table from csv files.

I have 5 csv files in a folder. all these csv files have multiple column with names like x,y,u,v....

I want to plot all u (In this case total 5 u will be there from five csv file) values in Matlab.

I am able to read and extract the column that contain u value from these csv files but not able to store it in array so that i can plot them on the same axis.

Can you please help!

Any help will be appreciated!

my code is

Folder='C:\Users\user\Desktop\7-19-22'

mat = dir(fullfile(Folder, '*.csv'));

disp(mat)

for files_i = 1:length(mat)

disp(mat(files_i).name)

data = fullfile(Folder,mat(files_i).name);

ReadCSV(data,files_i);

end

arr [];

function s = ReadCSV(data,i)

opts = detectImportOptions(data)

opts.SelectedVariableNames = {'u'};

T = readtable(data,opts);

disp(T)

end

Folder=pwd;  %'C:\Users\user\Desktop\7-19-22'
mat = dir(fullfile(Folder, '*.csv'));

uall = [];
for files_i = 1:length(mat)
    data = fullfile(Folder,mat(files_i).name); 
    x = readtable(data);
    uall =[uall x.u];
end

plot(uall)

@Chunru How you got the plots. When I ran the same code I am not getting any plots.

Use your own folder name where data files are stored:

Folder='C:\Users\user\Desktop\7-19-22'
