DWT with gaussian wavelet

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');
