You can perform wavelet analysis in matlab r and wavelet toolboxtm which lets you compute wavelet transform coefficientsthe toolbox includes many wavelet transforms that use wavelet frame representations such as continuous discrete nondecimated and stationary wavelet transforms. A shifted wavelet represented using this notation on screen means that the wavelet is shifted and centered at k we need to shift the wavelet to align with the feature we are looking for in a signal the two major transforms in wavelet analysis are continuous and discrete wavelet transforms. Cachcvcd dwt2xwname computes the single level 2 d discrete wavelet transform dwt of the input data x using the wname wavelet dwt2 returns the approximation coefficients matrix ca and detail coefficients matrices ch cv and cd horizontal vertical and diagonal respectively. Wt cwtx returns the continuous wavelet transform cwt of xthe input x is a double precision real or complex valued vector or a single variable regularly sampled timetable and must have at least four samplesthe cwt is obtained using the analytic morse wavelet with the symmetry parameter gamma equal to 3 and the time bandwidth product equal to 60
