Hey Ian - I hope I gave Cython a fair comment, but I have to add the disclaimer that your capability to understand/implement those solutions/workarounds in that project is greatly enhanced from your knowing the innards of Cython from being core developer on the Cython project. This doesn't detract

Re: [Numpy-discussion] State-of-the-art to use a C/C++ library from Python

We use Cython very heavily in DyND's Python bindings. It has worked well for us even when working with some very modern C++. That said, a lot depends on exactly which C++ features you want to expose as a part of the interface. Interfaces that require things like non-type template parameters or vari

Re: [Numpy-discussion] State-of-the-art to use a C/C++ library from Python

I just wanted to follow up on the C++ side of OP email - Cython has quite a few difficulties working with C++ code at the moment. It's really more of a C solution most of the time and you must split things up into a mostly C call interface (that is the C code Cython can call) and limit exposure/co

Hello, I have mesh (more exactly: just a bunch of nodes) description with values associated to the nodes in a file, e.g. for a 3x3 mesh: 0 0 10 0 0.3 11 0 0.6 12 0.3 0 20 0.3 0.3 21 0.3 0.6 22 0.6 0 30 0.6 0.3 31 0.6 0.6 32 What is best way to read it in and get data structures like

[Numpy-discussion] Include last element when subindexing numpy arrays?

Is there a clean way to include the last element when subindexing numpy arrays? Since the default behaviour of numpy arrays is to omit the “stop index”. So for, >>> A array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]) >>> A[0:5] array([0, 1, 2, 3, 4]) ___ NumPy-Dis
