Obtain the nondecimated (stationary) wavelet transform of a noisy frequency-modulated signal.
Obtain the wavelet packet transform of a 1-D signal. The example also demonstrates that frequency ordering is different from Paley ordering.
Use wfilters , wavefun , and wpfun to obtain the filters, wavelet, or wavelet packets corresponding to a particular wavelet family. You can visualize 2-D separable wavelets with wavefun2 .
Create and visualize a dictionary consisting of a Haar wavelet down to level 2.
Perform time-frequency analysis using the continuous wavelet transform (CWT). Continuous wavelet analysis provides a time-scale/time-frequency analysis of signals and images. The
Perform orthogonal matching pursuit on a 1-D input signal that contains a cusp.
