Any 2n × 2n symplectic matrix can be reduced to this condensed form which contains 8n − 4 nonzero entries and is determined by 4n − 1 parameters. The symplectic eigenvalue problem can be solved using the SR …

Thus, a butterfly transform of size N = 2 n will be fully specified by populating the 2 n − 1 nodes at levels 0 through n − 1 with butterfly matrices, where the butterfly matrices can be chosen subject only to the condition (12).
WebAnd the connection really is that matrices are used a lot when you are simulating things or when you're constructing things in computer science, especially in, frankly, computer graphics. So the super-intelligent robots that made the matrix in the movie Matrix were probably using matrices in order to do it, if they actually did exist.
