Misc
result = multi2index(subscripts, dimensions)
Translates multidimensional indices into flat indices (the inverse of ARRAY_INDICES).
Return value
Flat indices into an array with the given dimensions.
Parameters
- subscripts in
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 in
An array containing the length of each dimension in the multidimensional array.
Examples
If a is an LxMxN array, the following expressions are equivalent:
a[sub1, sub2, sub3]
a[ multi2index([sub1, sub2, sub3], [L, M, N]) ]
