Hi, this is a snippet for numerical inverse Laplace transform. You can find time response of a system expressed in F(s) form.



That one was well covered, two last remarks:
1. That Smath does not trig example [1], rather in terms of exp(,)
OK, unfamiliar ... but much faster as it involves only one numerical approximation.
Whatever: it's the Maple business, from which Smath depends upon.
2. last visit [red/cyan[ is sometimes of importance as demonstrated.

... when you deal with Laplace stuff, open your school book,
that will help setup Laplace Algebra appropriately, like this:

Hi. Improved version, works faster. Coefficients for the inversion are precalculated outside the inverter caller and avoiding vectorization for more compatibility of the inverter.

Thanks Alvaro,
Any real use for this old style inverser,
vs Maple export c/w parameters that works much faster.
Saludos ... Jean
