The GetHashCode method is used to provide a quick equality test when an object is used as a key in a IDictionaryTKey, TValue or IDictionary. Since a useful hash code of a matrix would need to involve all its elements, it is not possible to make this a fast operation. Also, since matrices are not immutable, they should not be used as hash keys. (A matrix might be changed after it had already been used as a key.) For these reasons, requesting a hash code for a matrix is not supported.
