您只需将代码修改为C++(而不是C)BOOST_PYTHON_MODULE(Spline)

{

import_array();

boost::python::numeric::array::set_module_and_type("numpy", "ndarray");

class_("Spline", init<>())

.def("spline", &Spline::spline)

;

}

因此在Python中可以使用：

^{pr2}$

Cpp等级：

^{3}$

然后在boost::python::list Spline::spline(numeric::array& x_val, numeric::array& y_val, double p)函数中得到：PyArrayObject* x_pyArr = (PyArrayObject*)PyArray_FROM_O(x_val.ptr());

PyArrayObject* y_pyArr = (PyArrayObject*)PyArray_FROM_O(y_val.ptr());

int size = *(x_pyArr->dimensions), i , j;

double* data_x = (double*)x_pyArr->data;

double* data_y = (double*)y_pyArr->data;

double h[NUMBER_OF_SAMPLES], a, b, c, d, s[NUMBER_OF_SAMPLES] = { 0 }, F[NUMBER_OF_SAMPLES], f[NUMBER_OF_SAMPLES], x[NUMBER_OF_SAMPLES], m[NUMBER_OF_SAMPLES][NUMBER_OF_SAMPLES] = { 0 }, temp;

for (int i = 0; i < size; i++)

{

x[i] = *(data_x + i);

f[i] = *(data_y + i);

}

依此类推。我在Spline::spline函数中返回一个python列表：boost::python::list return_val;

// ....

return_val.append(sum);

return_val.append(result);

return return_val;
