fresnel - calculation of the fresnel
integrals
Calling Sequence
-
K = fresnel(x)
Parameters
-
x
: scalar, vector or matrix with real values
-
K
: the fresnel integral K(x)=C(x) + %i*S(X)
Description
-
The calculation is not done by integration but by evaluation of
approximation and series.
Examples
x=linspace(-10,10,2000);
K=fresnel(x);
plot2d(real(K),imag(K),style=2);
