无论是Eigen::Matrix还是Eigen::Array都是2D数组,其他C++矩阵库如numcpp也不支持多维数组类型,想要在C++中延续Numpy高维数组(ndim ≥ 3)的诸多特性并不容易。Eigen其实在附加模块中实现了一个全新的数组类型Eigen::Tensor,可以支持多维数组的部分运算和功能,但是到目前为止并没有被官方加入到加入到Eigen的主干当中,而...

I see how to consume and alter a numpy.array (of doubles) binded to a py::array X by using X.request().shape to have the dimensions and then using static_cast<double*>(X.request().ptr) to get the coefficients. Now, I would like to implement a matrix (2D numpy.array) product (...
