LAPLACE Laplace transform.
L = LAPLACE(F) is the Laplace transform of the scalar sym F with
default independent variable t. The default return is a function
of s. If F = F(s), then LAPLACE returns a function of t: L = L(t).
By definition L(s) = int(F(t)*exp(-s*t),0,inf), where integration
occurs with respect to t.

L = LAPLACE(F,t) makes L a function of t instead of the default s:
LAPLACE(F,t) <=> L(t) = int(F(x)*exp(-t*x),0,inf).

L = LAPLACE(F,w,z) makes L a function of z instead of the
default s (integration with respect to w).
LAPLACE(F,w,z) <=> L(z) = int(F(w)*exp(-z*w),0,inf).

Examples:
syms a s t w x
laplace(t^5) returns 120/s^6
