Laplace and inverse laplace transform - dg1969 - 07-03-2014 07:58 PM
I'am not sure but before this 6030 firmware update this examples were ok ? laplace(f(t-a),t,s) => exp(-a.s).F(s) But with this firmware the cas on physical prime give the integral form... And now if I try : ilaplace(exp(-a.s).f(s),t,s) the result is : exp(-a.s)*f(s)*Dirac(t) Any idea ? Thank for comment. RE: Laplace and inverse laplace transform - parisse - 07-04-2014 06:30 AM
Should be s,t instead of t,s for ilaplace. I have never implemented something for laplace/ilaplace with a "symbolic" function (I mean something functional), only for fully defined expressions. |
