Two algorithms of evaluation of the continuous wavelet transform with the Morlet wavelet are presented. The first one is the solution of PDE with transformed signal, which plays a role of the initial value. The second allows to explore the influence of central frequency variation via the diffusion smoothing of the data modulated by the harmonic functions. These approaches are illustrated by the analysis of the chaotic oscillations of the coupled Roessler systems
