The Laplace(expr, a(n)) command computes the Laplace transform of a generating function.

If  is the sequence of numbers defined by the recurrence expr, the Laplace function computes the recurrence for the numbers .

If t is specified as 'diffeq', expr is considered a linear differential equation with polynomial coefficients. The function returns a linear differential equation satisfied by its Laplace transform.

The invborel command can be used as a synonym of Laplace, that is, the invborel(expr, a(n)) command can be used instead.
