Joint Probability Density
for entropyH = entropy(S)this command will evaluate the entropy of S, S should be row matrixH = entropy([X;Y;Z])this command will find the joint entropy for the 3 variablesH = entropy([X,Y],[Z,W])this will find H(X,Y/Z,W).. you can use it for any combination of joint entropiesPlease validate this...

This program calculates the Vibration Response Spectrum (VRS) for a base input Power Spectral Density (PSD).The base input PSD must be in terms of acceleration.The VRS uses point-by-point multiplication of the transmissibility function times the base input PSD. It is thus more accurate than Miles...
