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
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.
If on entry
, explanatory error messages are output on the current error message unit (as defined by X04AAF
E04REF is not threaded in any implementation.
See Section 10
in E04RAF for links to all examples in the suite.
