Hie all, If i have a set of data for power quality, and i would like to use s-transform in matlab to implement the detection. Can anyone guide me where am i suppose to start?and how to implement s-tranform in matlab?
THANKS, EAN

hey, i've just started working on s-transform to recognize power system disturbance. Can u please give me a set of power quality data if u have any? And if u have successfully succeeded on implementing the transform, can u please guide me briefly through the process on how u've done it??

Is s-transform the same as Laplace transform? (A quick web search suggests to me that it is.) If so, then you can use the laplace() function in the Symbolic Math Toolbox. There are examples in the documentation here:

I'm quite new to this transform but this is what i know so far. The S-transform is quite different from the Laplace transform. Laplace can be used to convert differential equations into algebraic ones whereas S-transform is a time-frequency representation of a signal (mostly used for non-stationary ones) which is the phase correction of the continuous wavelet transform (CWT). Please correct me if i'm wrong.
