One of the important aspects of REST (or at least HTTP) is the concept that some operations (verbs) are idempotent. As Gregor Roth said several years ago: The PUT method is idempotent. An idempotent method means that the result of a successful performed request is independent of the number of times it is executed. Idempotency is also something discussed in the SOA Design Patterns.
A singular matrix is a matrix that is not invertible. If a matrix is not invertible, then: â¢ The determinant of the matrix is 0. â¢ Any matrix multiplied by that matrix doe â¦ sn't give the identity matrix. There are a lot of examples in which a singular matrix is an idempotent matrix. For instance: M = [1 1] [0 0] Take the product of two M's to get the same M, the given! M x M = M So yes, SOME singular matrices are idempotent matrices!
