rLSgetNLPData: Get data about the nonlinear structure of a model.

In rLindo: R Interface to LINDO API

Description

R interface function for LINDO API function LSgetNLPData. For more information, please refer to LINDO API User Manual.

Usage

  rLSgetNLPData(model)

Arguments

model

A LINDO API model object, returned by rLScreateModel.

Value

An R list object with components:

ErrorCode	Zero if successful, nonzero otherwise.
paiNLPcols	An integer array containing the index of the first nonlinear nonzero in each column.
panNLPcols	An integer array containing the number of nonlinear elements in each column.
padNLPcoef	A double array containing the current values of the nonzero coefficients in the (Jacobian) matrix.
paiNLProws	An integer array containing the row indices of the nonlinear nonzeros in the coefficient matrix.
pnNLPobj	Number of nonlinear variables in the objective function.
paiNLPobj	An integer array containing column indices of the nonlinear terms in the objective.
padNLPobj	A double array containing the current partial derivatives of the objective corresponding to the variables in paiNLPobj.
pachNLPConTypes	A character array whose elements indicate whether a constraint has nonlinear terms or not.If pachNLPConTypes[i] > 0, then constraint i has nonlinear terms.
