I am looking for a way to create an array of the same type as another
given array (but of different shape) that works both with Numeric and
NumPy without being unreasonably slow. In other words, I am looking
for a a replacement for the expression
array2 = Numeric.zeros(shape, array1.typecode())
that will *also* (not *only*) work under NumPy (where typecode()
became dtype.char). An obvious idea is reshaping array1 and
multiplying by 0., but that can become quite costly.
Any ideas?
Konrad.
