How to import data from .txt file?

Hello everyone,

I am doing an application on App Designer and I need to extract data from a simple txt file architecture (as shown below). After extracted the data, I need to save them on a matlab file but I don't find the way to do that.

I code this but it's not working

[filename,pathname]=uigetfile({'*.fl.txt' 'Torque file (*.fl.txt)'},'Select a torque curve');
            
            if filename ~= 0
            
                extracted=textscan([filename,pathname],'%f %f')
                CDC_N=extracted(:,1)
                CDC_Torque=extracted(:,2)
                save(CDC.mat,'CDC_N','CDC_Torque');
            
            end

if anyone could help me, I'd be grateful.

thanks

The textscan function expects a fileID, not a file name. you need to use fopen.

[filename,pathname]=uigetfile({'*.fl.txt' 'Torque file (*.fl.txt)'},'Select a torque curve');
            
            if filename ~= 0
                fid = fopen(fullfile(pathname,filename));
                extracted=textscan(fid,'%f %f');
                fclose(fid);
                CDC_N=extracted(:,1)
                CDC_Torque=extracted(:,2)
                save(CDC.mat,'CDC_N','CDC_Torque');
            end
