MQuadExpr.item()
item ( )
For an MQuadExpr that contains a single element, returns a copy of that element as a QuadExpr object. Calling this method on an MQuadExpr with more than one element will raise a ValueError.
Return value:
A QuadExpr object
Example usage:
mqe = 2 * model.addMVar((2, 2))** + 1 mqe_sub = mqe[0, 1] # A 0-D MQuadExpr encapsulating one QuadExpr object mqe_qe = mqe[0, 1].item() # A copy of the resident QuadExpr object
