The required subroutines are contained incomplex.c, muller.c, newton.c, and tools.c. The file rootsl.c is a MATLAB (version 4) gateway file. The file rootsl.mex4 is an executable(on SUN workstations) mex file. To create a mex file for other machines use the 'makefile' (might require some modifications). Please notethat we use ANSI C. You may create a shell executable by the command 'gcc -ansi test.c null.c muller.c complex.c tools.c newton.c -lm'.The main (MATLAB) routine for spectral factorization is factorize.m.REFERENCES:  Markus Lang, Bernhard-Christian Frenzel.
