[julia-users] Ravel/Unravel Index

[Christoph Ortner]

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