Hello everyone
How it is possible to use 1-derivative of Gaussian function as the wavelet in dwt?
I know that Gaussian wavelet family exists in Matlab but it complains when I write:
load noisdopp; [A,D] = dwt(noisdopp,'gaus');
and says: Invalid argument value. but from waveinfo we know that such wavelet is existed.
Is there any way to define this wavelet for dwt?

[A,D] = dwt(noisdopp,'gaus');
