The Laplace transform, named after its inventor Pierre-Simon Laplace , is
an integral transform that converts a function of a real variable (often time)
to a function of a complex variable {s} (complex frequency).
The transform has many applications in science and engineering because it
is a tool for solving differential equations. In particular, it transforms
differential equations into algebraic equations and convolution into
multiplication.
The Laplace transform has a number of properties that make
it useful for analyzing linear dynamical systems. .
The transform turns integral equations and differential
equations to polynomial equations, which are much easier to
solve. Once solved, use of the inverse Laplace
transform reverts to the original domain.
