Gaussian wavelet

Syntax

```
[PSI,X] = gauswavf(LB,UB,N,P)
```

Description

[PSI,X] = gauswavf(LB,UB,N,P) returns values of the P-th derivative of the 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, Symbolic Math Toolbox™ software is required.

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

[PSI,X] = gauswavf(LB,UB,N) is equivalent to [PSI,X] = gauswavf(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 Gaussian wavelet of order 8.
[psi,x] = gauswavf(lb,ub,n,8);

% Plot Gaussian wavelet of order 8.
plot(x,psi),
