Syntax
[PSI,X] = cgauwavf(LB,UB,N,P)
Description
[PSI,X] = cgauwavf(LB,UB,N,P) returns values of the P-th derivative of the complex Gaussian function
on an N point regular grid for the interval [LB,UB]. Cp is such that the 2-norm of the P-th derivative of F is equal to 1.
For P > 8, the Extended Symbolic Toolbox will be required.
Output arguments are the wavelet function PSI computed on the grid X.
[PSI,X] = cgauwavf(LB,UB,N) is equivalent to
[PSI,X] = cgauwavf(LB,UB,N,1)
These wavelets have an effective support of [-5 5].
Examples
% Set effective support and grid parameters.
lb = -5; ub = 5; n = 1000;
% Compute complex Gaussian wavelet of order 4.
[psi,x] = cgauwavf(lb,ub,n,4);
% Plot complex Gaussian wavelet of order 4.
