Create Python Bindings with Cython Dennis

WebPointer types are constructed as in C, by appending a * to the base type they point to, e.g. int** for a pointer to a pointer to a C int. Arrays use the normal C array syntax, e.g. int [10]. Note that Cython uses array access for pointer dereferencing, as *x is not valid Python syntax, whereas x [0] is. Web我正在從C切換到C ++，並且我想最佳地使用可用的附加功能，並避免使用諸如void *指針之類的“ C風格”東西。 具體來說，我正在嘗試制作類似gsl_function的接口（不是在C ++中使用gsl的包裝器）。. 在C語言中，我編寫了一些用於根查找，集成的例程，這些例程使用類似gsl_function的接口將數學函數傳遞給 ... how to take care of paperwhites

Numpy-＞Cython转换。编译错误:无法将

WebCython gives you many choices of sequences: you could have a Python list, a numpy array, a memory view, a C++ vector, or a pointer. Pointers are preferred, because they are fastest, have the most explicit semantics, and let the compiler check your code more strictly. C++ vectors are also great — but you should only use them internally in functions.
