Query the value of an attribute for a matrix constraint. The full list of available attributes can be found in the Attributes section.
Raises an AttributeError if the requested attribute doesn't
exist or can't be queried.
Raises a GurobiError if there is a problem with the
MConstr object (e.g., it was removed from the model).
The result is returned as a NumPy ndarray with the same shape as the
MConstr object.
Arguments:
attrname: The attribute being queried.
Return value:
ndarray of current values for the requested attribute.
Example usage:
mc = model.addConstr(A @ x <= b)
rhs = mc.getAttr("RHS")
