After the model has been fully or partially built by calling functions of the NAG optimization modelling suite, e04tjc
may be used to set or modify a single element
in the sparse linear constraint matrix
previously defined by e04rjc
. This might be particularly helpful when a linear constraint needs to be extended after new variables have been added to the model by e04tac
See Section 4.1
in the E04
Chapter Introduction for more details about the NAG optimization modelling suite.
