This article presents and illustrates the applicability of the NASA program for the Nonlocal Automated Sensitivity Analysis of parameterized nonlinear systems F(x,b)=0 over parameter intervals [b0,b1]. The NASA program incorporates automated procedures for initialization, derivative evaluation, and the tracking of solution branches x(b) along user-designated paths for the parameter vector b.
