XPRBnewarrvar

Purpose

Create a one-dimensional array of variables.

Synopsis

XPRBarrvar XPRBnewarrvar(XPRBprob prob, int nbvar, int type, const char *name, double bdl, double bdu);

Arguments

prob

Reference to a problem.

nbvar

Size of the array of variables.

type

Type of the variables, which may be one of:

XPRB_PL	continuous;
XPRB_BV	binary;
XPRB_UI	general integer;
XPRB_PI	partial integer;
XPRB_SC	semi-continuous;
XPRB_SI	semi-continuous integer.

name

The array name. May be NULL if not required.

bdl

Variable lower bound.

bdu

Variable upper bound.

Return value

Reference to the new array of variables if function executed successfully, NULL otherwise.

Example

The following defines an array of ten continuous variables between 0 and 500, with names beginning arry1 followed by a counter.

XPRBprob prob;
XPRBarrvar ty1;
   ...
ty1 = XPRBnewarrvar(prob, 10, XPRB_PL, "arry1", 0, 500);

Further information

1. This function creates a single-indexed array of variables. Individual bounds on variables may be changed afterwards using XPRBsetlb and XPRBsetub, and variable types by using XPRBsetvartype. The function returns the BCL reference to the array of variables. If name is defined, BCL generates names for the variables in the array by adding an index to the string. If no array name is given, BCL generates a default name starting with AV. (The generation of unique names will only take place if the names dictionary is enabled, see XPRBsetdictionarysize.)

2. Either of the bounds XPRB_INFINITY or -XPRB_INFINITY for plus or minus infinity may be used for the arguments bdu and bdl.
