Set the values of an integer-valued array attribute.
Return value:
A non-zero return value indicates that a problem occurred while setting the attribute. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.
Arguments:
model: A loaded optimization model, typically created by routine GRBnewmodel or GRBreadmodel.
attrname: The name of an integer-valued array attribute. Available attributes are listed and described in the Attributes section of this document.
start: The index of the first entry in the array to set.
len: The number of array entries to set.
values: A pointer to the desired new values for the specified sub-array of the attribute. Note that the values array must be as long as the sub-array to be changed.
Example usage:
int cbasis[] = {GRB_BASIC, GRB_BASIC, GRB_NONBASIC_LOWER, GRB_BASIC};
error = GRBsetintattrarray(model, "CBasis", 0, 4, cbasis);
