👉 Retrograde, in mathematics and computer science, refers to a process or procedure that moves an element backward in time by one step. This is often used to refer to the reverse of an operation, where elements are moved backwards through a sequence of operations. For example, if we have a program that performs some operation on a list of numbers, the "retrograde" version of this process would be to reverse the order of the elements in the list and then perform the same operation again.
