E04REF is a part of the NAG optimization modelling suite and defines the linear objective function of the problem.
After the initialization routine
E04RAF has been called, E04REF may be used to define the objective function of the problem as a linear function
${c}^{\mathrm{T}}x$ unless the objective function has already been defined by E04REF,
E04RFF or by
E04RGF. This will typically be used for linear semidefinite programming problems (SDP)
or SDP with bilinear matrix inequalities (BMI-SDP) where the objective function has only linear terms. See
E04RAF for more details.
None.
If on entry
${\mathbf{IFAIL}}=0$ or
$-1$, explanatory error messages are output on the current error message unit (as defined by
X04AAF).
Not applicable.
E04REF is not threaded in any implementation.
None.
