Then, by the Cauchy integral formula for a region [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] we have:
Then the values of f (z), for z [member of] G, can be computed by the Cauchy integral formula.
The values of the function f (z) for interior points z [member of] G can be computed by the Cauchy integral formula.
Computing the interior values requires computing the Cauchy integral formula.
Computing these functions at interior points z [member of] G requires the Cauchy integral formula
function fz = fcau (et,etp,f,z,n,finf) %The function % fz = fcau (et,etp,f,z,n,finf) %returns the values of the analytic function f computed %using the Cauchy integral formula at interior vector of %points z, where et is the parameterization of the boundary, %etp=et', finf is the values of f at infinity for %unbounded G, n is the number of nodes in each boundary component.
n](z) for z [member of] G are calculated by the Cauchy integral formula.
Emphasizing how complex analysis is a natural outgrowth of multivariable real calculus, this graduate textbook introduces the Cauchy integral formula, the properties and behavior of holomorphic functions, harmonic functions, analytic continuation, topology, Mergelyan's theorem, Hilbert spaces, and the prime number theorem.
