[Blitz-support] minIndex and maxIndex return tiny(int()) if whole Array filled with tiny(Type())

[Thorsten S. <tsc...@in...>]

Dear Sir or Madam.

While working with the blitz++ Library I found the following unintuitive
behaviour:

If an Array of Type T is completely filled with the minimal Value of
that Type the functions minIndex and maxIndex return as Index a
TinyVector containing only INT_MIN as entries. E.g.:

Array<unsigned char,2> A(2,2);
A=3D0;
cout << "minIndex(A) =3D " << minIndex(A) << endl;

gives

minIndex(A) =3D 2 [ -2147483648-2147483648 ]


2 [ 0 0 ] (or any other valid index) would make more sense to me. If
that behaviour is intentional, ignore this mail, otherwise I would
suggest to replace the initialization of the indices in reduce.h to 0
instead of tiny(int()).

Best regards.

Thorsten Schmidt.
