Fast adaptive polynomial root tracking using a homotopy continuation method
1993 IEEE International Conference on Acoustics, Speech, and Signal Processing.
A fast adaptive method for tracking the roots of a time-varying complex domain polynomial is derived. The approach uses the method of homotopy continuation and is efficient from both mathematical and implementation standpoints. The method is globally convergent and tracks all roots simultaneously. An example that verifies the accurate tracking ability of the algorithm is presented. Applications which could benefit from this method are also discussed. >
