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);
