Scilab Function

ugrsh - unconstrained tool, gradient and Hessian sparse matrix

Calling Sequence

[NNZH,G,SH,ICNH,IRNH,SP] = ugrsh(X)

Parameters

Description

ugrsh evaluates the gradient and the Hessian matrix of the objective function of the problem decoded into OUTSDIF.d at the point X in the case where the only possible constraints are bound constraints. This Hessian matrix is stored as a sparse matrix in coordinate format. SPARSE gives the symetrical sparse matrix in scilab format
