Purpose
CVodeGet
CVodeGet extracts data from the CVODES solver memory.
Synopsis
function varargout = CVodeGet(key, varargin)
Description
CVodeGet extracts data from the CVODES solver memory.
Usage: RET = CVodeGet ( KEY [, P1 [, P2] ... ])
CVodeGet returns internal CVODES information based on KEY. For some values
of KEY, additional arguments may be required and/or more than one output is
returned.
KEY is a string and should be one of:
o DerivSolution - Returns a vector containing the K-th order derivative
of the solution at time T. The time T and order K must be passed through
the input arguments P1 and P2, respectively:
DKY = CVodeGet(’DerivSolution’, T, K)
o ErrorWeights - Returns a vector containing the error weights.
EWT = CVodeGet(’ErrorWeights’)
o CheckPointsInfo - Returns an array of structures with check point information.
