Re: [Numpy-discussion] ufunc for user-defined type

Neal Becker wrote:

Now that I have my user-defined type, I want to add some funcs. According to the numpy book, I need to use:

PyUFunc_RegisterLoopForType

The book says I first need a ufunc. The only way I see to create one is

PyUFunc_FromFuncAndData.

Is the the correct procedure?

You'll have to do some digging because the API allowing low-level loops for user-defined types is not well tested or vetted. Also, don't be surprised if you uncover some bugs. The concept is that you create the UFunc with the "built-in" types using PyUFunc_FromFuncAndData and then you add loops for the user-defined type using RegisterLoopForType. So, you have the basic procedure down. -Travis
