mexhat

Mexican hat wavelet in time domain

Calling Sequence

[H,T] = mexhat()
[H,T] = mexhat(NU)

Parameters

NU :

a scalar in [0 0.5] (default : 0.05).

H :

a real row vector of length 2*ceil(1.5/NU)+1: the the mexhat time samples.

T :

a real row vector of length 2*ceil(1.5/NU)+1: the mexican hat time support.

Description

mexhat returns the mexican hat wavelet with central frequency NU (NU is a normalized frequency in Hz).

Examples

clf
plot(mexhat(0.05));
