LaplaceTransform

gives the Laplace transform of expr.

gives the multidimensional Laplace transform of expr.

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. »

Assumptions and other options to Integrate can also be given in LaplaceTransform. »
