[Numpy-discussion] Getting the indexes of the myarray.min()

[T. C. <al...@an...>]

Hello,

I am new to numarray. I have been searching the documentation, and see
no evident vectorial and concise way to get the indexes for the minimum
of an array times.min().

Currently my two alternatives are: (times is NxN array)

husband, wife =3D nonzero(equal(times.min(),times))=20
#gives tuple of 1x1 arrays, each containing one index

and (even uglier)

husband =3D compress(times.min()=3D=3Dtimes,indices([N,N])[0])
wife    =3D compress(times.min()=3D=3Dtimes,indices([N,N])[1])

These are weird ways to get something as simple. I am surely missing
something, but I have tried several slicing strategies before without
success.

For getting the minimum times in each row I use:

choose(argmin(times),transpose(times))

What are the idioms in numpy for these tasks?


Thank you very much in advance, =E1.
