Morlet wavelet

Syntax

• [PSI,X] = morlet(LB,UB,N) 
  

Description

[PSI,X] = morlet(LB,UB,N) returns values of the Morlet wavelet on an N point regular grid in the interval [LB,UB].

Output arguments are the wavelet function PSI computed on the grid X, and the grid X.

This wavelet has [-4 4] as effective support.

Examples

• % Set effective support and grid parameters. 
  lb = -4; ub = 4; n = 1000; 
  % Compute and plot Morlet wavelet. 
  [psi,x] = morlet(lb,ub,n); 
  plot(x,psi), title('Morlet wavelet')
