Haar wavelet transform plots at different scales and translation

Hi ,

I want to plot haar wavelet at different scales and transalation (just for an example) using MATLAB.I am new to the wavelets and dont know how and where to start.

I am attaching a pic of what kind of plots I want.

Any help will be appreciated.

The below code gives you one of the required graph

Here a=1,b=0

waveinfo('haar')
[psi,phi,xval] = wavefun('haar',0);
plot(xval,phi);
