* Calculus : Laplace transform.

************

Windows : Dev-C++ 4
Linux : gcc abc.c -lm Return
a.out Return

************

* You can compile the *.c files directly without create a project.

************

Verify the laplace transform with some examples.

c10j_1a.c fa.h : without parameter.
c10j_1b.c fb.h
c10j_1c.c fc.h


c10j_2f.c fa.h : with one parameter.
c10j_2g.c fb.h

c10j_3j.c fa.h : with two parameters.


example :


/ oo
|
| exp(-st) F(t) dt = 0.230769226920
|
/ 0

f(+5.000) = 0.230769230769

With


F(t) t-> exp(P2*t) * cos(P1*t)

f(s) s-> (s-P2) / ((s-P2)^2 + P1^2) (Laplace transform of F(t))
