cfn

CFN − CUTEr tool to evaluate function and constraints values.

CALL CFN( N, M, X, F, LC, C )

The CFN subroutine evaluates the value of the objective function and general constraint functions of the problem decoded into OUTSDIF.d at the point X, in the constrained programming case.

The arguments of CFN are as follows

N [in] - integer

the number of variables for the problem,

M [in] - integer

the total number of general constraints,

X [in] - real/double precision

an array which gives the current estimate of the solution of the problem,

F [out] - real/double precision

the value of the objective function evaluated at X,

C [out] - real/double precision

an array which gives the values of the general constraint functions evaluated at X. The i-th component of C will contain the value of c_i (x),

LC [in] - integer

is the actual declared dimension of C, with LC no smaller than M.
