Cauchy integral
[y]=intl(a,b,z0,r,f)
a complex number
two real numbers
positive real number
"external" function
If f
is a complex-valued function,
intl(a,b,z0,r,f)
computes the integral of
f(z)dz
along the curve in the complex plane defined by
z0 + r.*exp(%i*t)
for a<=t<=b
.(part of the circle with center z0
and radius
r
with phase between a
and
b
).
