               nrows, rhs = NULL, sense = NULL,
               rngval = NULL, rnames = NULL)

Arguments

env

An object of class "'>cplexPtr" as returned by openEnvCPLEX. This is basically a pointer to an IBM ILOG CPLEX environment.

lp

nrows

Number of new rows.

rhs

Right hand side term for each new constraint.

sense
