Mellin transform


The Mellin transformDlmfMathworldPlanetmath is an integral transformDlmfMathworld defined as follows:

F(s)=0f(t)ts-1𝑑t

Intuitively, it may be viewed as a continuousMathworldPlanetmath analogue of a power series — instead of synthetizing a functionMathworldPlanetmath by summing multiples of integer powers, we integrate over all real powers. This transform is closely related to the Laplace transformDlmfMathworldPlanetmath — if we make a change of variables t=e-r and define g by f(e-r)=g(r), then the above integralDlmfPlanetmath becomes

F(s)=--+g(r)e-rs𝑑r,

which is a bilateral Laplace transform.
