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)
