In mathematics and computer programming, Index notation is used to specify the elements of an array of numbers. The terms "index notation", or "indicial notation" are sometimes used to refer to Einstein notation. The formalism of how indices are used varies according to the subject. In particular, there are different methods for referring to the elements of a list, a vector, or a matrix, depending on whether one is writing a formal mathematical paper for publication, or when one is writing a computer program.

This is not to be confused with "index form" which is the writing of prime factorizations using exponents.
