Instab implements functional stability analysis, , which uses the relationship between the forward error, the backward error, , and a problem's condition to define a function that estimates a lower bound , on the backward error. The subplex optimization method then maximizes the function. , A numerical algorithm is unstable if the maximization shows that the backward error , can become large. Since numerical algorithms are treated as black boxes, Instab , normally requires little more than an executable version of a numerical algorithm , to determine if it is unstable. by Tom Rowan <na.rowan@na-net.ornl.gov> lang fortran size 24K file intel/README.txt for README for Intel(R) Decimal Floating-Point Math Library file intel/IntelRDFPMathLib10U1.tar for Intel(R) Decimal Floating-Point Math Library file iqpack for Fortran subroutines for the weights of interpolatory quadratures , the package is an implementation of the method described in , "Calculation of the Weights of Interpolatory Quadratures", , J.
