intl
====

Cauchy integral



Calling Sequence
~~~~~~~~~~~~~~~~


::

    [y]=intl(a,b,z0,r,f)




Arguments
~~~~~~~~~

:z0 a 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`).
