Thank very good
However, there is something that I do not understand
I define
W1=0.2
z(x) = (x + W1*{0,1})
w(x) = faddeeva (z (x))
and
Voi (x) = voigt (x, W1)
Voi (x) and real (w(x)) are exactly the same
Now,
d_w (x) = - 2 * z (x) * w (z (x)) + 2*{0,1}/sqrt(pi) " which is the derivative
D_voi(x,del) = (Voi (x+del) - Voi (x-del)) / 2 / del
now
plot [-4:4] D_voi(x,0.001)
and
plot [-4:4] real (d_w (x))
are different except for W1=0
What am I doing wrong?
It seems that the issue is with the faddeeva, or when I my calls!
Thank.
