Error when load file .dat in matlab

Question

I have problem when I try to load file .dat in Matlab. My file .dat about speech data:

% Read data file "orig.dat" with sampling rate of 8 kHz
% create an example sound
fs=8000;
t=0:1/fs:3;
x = 1*sin(2*pi*4*t)+0.25* sin(2*pi*560*t);
% play it back
%sound(x, 8000);
wavwrite(x,fs,16,'test56.wav');
y=wavread('test56.wav')
save y.dat y
load y.dat

There is a error:

??? Error using ==> load Number of columns on line 1 of ASCII file C:\Program Files\MATLAB\R2010b\bin\doan\y.dat
must be the same as previous lines.
Error in ==> twosubband at 8 load y.dat; % Load speech data

I don't understand. Help me fix it.

load expects a file in its own data format. Try saving y as y.mat instead of y.dat. That is, replace y.dat in both the line where you save and the line where you load by y.mat.

That should do the trick.
