Estimate radius of convergence of a real-valued Taylor series from its coefficients when convergence is limited by singularities.

Estimate radius of convergence of a real-valued Taylor

series from its coefficients when convergence is limited

by either a real singularity or a complex conjugate pair

of singularities. Execute with no argument to see an

example. Also estimate the location and nature of the

singularities---assuming they are of form [z-r]^nature or

[z-r*exp(i*theta)]^nature. See Appendix of the article by
