WebOne important thing to note about SymPy matrices is that, unlike every other object in SymPy, they are mutable. This means that they can be modified in place, as we will see below. The downside to this is that Matrix cannot be used in places that require immutability, such as inside other SymPy expressions or as keys to dictionaries. If you ...
