Set the values of a character-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 a character-valued array attribute. Available attributes are listed and described in the Attributes section of this document.
len: The number of array entries to set.
ind: The indices of the array attribute elements that will be set.
values: A pointer to the desired new values for the specified elements of the attribute. Note that the values array must be as long as the list of indices.
Example usage:
int change[] = {0, 1, 3};
char vtypes[] = {GRB_BINARY, GRB_BINARY, GRB_BINARY};
error = GRBsetcharattrlist(model, "Vtype", 3, change, vtypes);
