MATLAB: Read time and numerical data from txt file and plot in matlab.

Question

Hello,

Previously, I saved mydata.txt in .xlsx (excel format) and used:-

data=xlsread('mydata.xlsx');
ax=(data(:,3))';
ay=(data(:,4))';
az=(data(:,5))';
bx=(data(:,6))';
by=(data(:,7))';
bz=(data(:,8))';
time=t=(data(:,2))';
%plot(t,ax,'y-',t,ay,'r-',t,az,'m-',t,bx,'+-',t,by,'o-',t,bz,'*-');

Instead of use xlsread is there any other method to directly read txt file?
