Open in MATLAB Online The Curve Fitting Toolbox does not accept complex valued functions. To carry out the fit, use the LSQNONLIN function or the FMINSEARCH function. The objective function passed to LSQNONLIN or FMINSEARCH should take the real and complex parts of the parameters separate...
Stationary complex-valued functionals are discussed and seen to have unique stationary points if they are analytic, which corresponds to analyticity of functions in complex-valued function theory. As an application, the problem of wave propagation in a circular waveguide with an impedance boundary and...
Next, we prove that every unital endomorphism of real Lipschitz algebras of complex-valued functions on compact metric spaces with Lipschitz involutions is a composition operator. Finally, we study some properties of quasicompact and Riesz unital endomorphisms of these algebras. 展开 ...
