![]() The following definition provides a sufficient condition on the function f to possess the Laplace transform. But for integrability of the product \( f(t)\, e^ \) on the semi-infinite interval [0, ∞), we need a stronger condition than piecewise continuity. It is known in calculus that if a function f is intermittent on a finite closed (compact) interval, then it is integrable on that interval. Then its Laplace transform f(s) exists for all s > 0, where 0 is the abscissa of convergence of f(t). Set(H2,'Facecolor',) Ībscissa of convergence and the domain of convergence for a Laplace transformation. H2=area(ah,areaInterval,f(areaInterval))
