LaplaceTransform
LaplaceTransform
gives the Laplace transform of
expr
.
LaplaceTransform
gives the multidimensional Laplace transform of
expr
.
MORE INFORMATION
The Laplace transform of a function
is defined to be
.
The lower limit of the integral is effectively taken to be
, so that the Laplace transform of the Dirac delta function
is equal to 1.
