I tried to obtain my scaling and wavelet functions by typing the command:
[phi,psi,xval] = wavefun('haar',4)
at the MATLAB command prompt.
Using the command above, my results always have 18 points instead of 2^4 or 16 points that I have expected.
phi = Columns 1 through 10 0 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 Columns 11 through 18 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 0 psi = Columns 1 through 10 0 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 -1.0000 Columns 11 through 18 -1.0000 -1.0000 -1.0000 -1.0000 -1.0000 -1.0000 -1.0000 0 xval = Columns 1 through 10 0 0.0625 0.1250 0.1875 0.2500 0.3125 0.3750 0.4375 0.5000 0.5625 Columns 11 through 18 0.6250 0.6875 0.7500 0.8125 0.8750 0.9375 1.0000 1.0625
