Ravel does make a copy when the array is not contiguous. I asked this question before but didn't get any response - is there a way to get the argmax/min or max/min of a non-contiguous multi-dimensional array without making a contiguous copy? I use python as an interface to fortran code and so I am constantly dealing with arrays that are not contiguous, i.e. not with C ordering. Any help is appreciated.
  Thanks,

You could run it on Numeric.ravel(array) (which shouldn't make a
copy), and then reconstruct the multidimensional indices from the
single index into the flattened array. The additional overhead
should be minimal, and you don't need any C code.
