Syntax
Description
L = laplace(F)
is the Laplace transform of the scalar symbol F
with default independent variable t
. The default return is a function of s
. The Laplace transform is applied to a function of t
and returns a function of s
.
If F = F(s)
, laplace
returns a function of t
.
where t
is the symbolic variable in F
as determined by findsym
.
L = laplace(F,t)
makes L
a function of t
instead of the default s
.
Here L
is returned as a scalar symbol.
L = laplace(F,w,z)
makes L
a function of z
and F
a function of w
instead of the default variables s
and t
, respectively.
