RESUMO
We present a software to invert functions from the plane to the plane F(x) = b, for a generic smooth function F, as well as the theory to implement it. In principle, all points in the preimage of b are computed. The numerical inversion is based on the characterization of the critical set C = {x pertence R2 : detDF(x) = 0} and its image, and in appropriate techniques of numerical continuation in situations of controlled interaction with C. A graphical user interface allows for the study of local and global properties of the function, both of geometric and analytic nature.
