Ravel/Unravel Index

[Christoph Ortner]

Does Julia have an analogue of Python's   `numpy.unravel_index`  and  `numpy.ravel_multi_index`   ; see
     http://docs.scipy.org/doc/numpy/reference/generated/numpy.unravel_index.html

Probably easy to write, but if there is an existing efficient implementation then I'd like to use it.

My application is that I have an array A,  of which I do not know the dimensionality beforehand. Hence I loop

for n = 1:length(A)

     . . .

end

    

but can still access the multi-index corresponding to n inside the loop.

Thank you,

     Christoph

I think the equivalents are ind2sub and sub2ind

For once I think that Matlab has the better names.
