How to read in a .txt and arrange the data into a scheme?

Hi, I have some problem with reading in a txt file, I have to read in a txt file with about 7000 records, 1 headerline. After reading with textscan how can I arrange the datas into arrays or sg like that to do some postprocess and ploting with them?

fid = fopen(filename,'r');
cdata = textscan(fid,'%f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f','Delimiter','\t','headerLines',1);

Thanks

I try to use readcell as follows:

rawdata=readcell('test1.txt');
header = rawdata(1,:);
data = cell2mat(rawdata(2:end,:));
tiledlayout(5,6);
for k = 1:27
	nexttile
	plot(data(:,1),data(:,k+1));
	ylabel(header{k+1});
	xlabel(header{1});
end

Thank you, can you please help me, if I want to plot for example accelerations on one graph with other colors? e.g acc_x with red, acc_y with blue and acc_z with green and for magneto and gyro too. Thanks

I am not sure which gyro you want, but you can modify the code yourself to suit your purpose:

figure
plot(data(:,1),data(:,11),'r',data(:,1),data(:,12),'b',data(:,1),data(:,13),'g')
legend(header{11:13})
xlabel(header{1});

hello

this is the best solution (IMO) : it will generate a table with identified variables names you can easily access :

T= readtable('test1.txt');

% if we want to plot data (example) 
time = T.SampleTime_s_;
Gyro_1_X_dps_ = T.Gyro_1_X_dps_;

plot(time,Gyro_1_X_dps_);  % and so forth...
