morlet (Wavelet Toolbox)

Morlet wavelet.

[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, X, on 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')
