Name
intl — Cauchy integral
Calling Sequence
[y]=intl(a,b,z0,r,f)
Parameters
- z0
complex number
- a,b
two real numbers
- r
positive real number
- f
"external" function
Description
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
)
