MQConstr.getAttr()

getAttr ( attrname )

Query the value of an attribute for a matrix quadratic 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 MQConstr object (e.g., it was removed from the model).

The result is returned as a NumPy ndarray with the same shape as the MQConstr object.

Arguments:

attrname: The attribute being queried.

Return value:

ndarray of current values for the requested attribute.

Example usage:

  mqc = model.addConstr(x**2 + y <= 1)
  qcrhs = mc.getAttr("QCRHS")
