MULTI2INDEX

MULTI2INDEX

Name


    MULTI2INDEX

Purpose


    Translates multidimensional indices into flat indices (the inverse
    of ARRAY_INDICES).

Category


    Misc

Calling Sequence


    Result = MULTI2INDEX(Subscripts, Dimensions)

Inputs


    Subscripts: Multidimensional indices. If Dimensions has D
                  elements, then Subscripts is a DxQ dimensional
                  array to translate Q sets of indices. Q may be
                  1 (or, equivalently, missing).
    Dimensions: An array containing the length of each dimension in
                  the multidimensional array.

Outputs


    Flat indices into an array with the given dimensions.

Example


    If a is an LxMxN array, the following expressions are equivalent:
    a[sub1, sub2, sub3]
    a[ multi2index([sub1, sub2, sub3], [L, M, N]) ]
