// 直接 reshape, 发现是 column-major // 以及是不是有点麻烦, 还必须显式地写一个 Eigen::array 其实就是 std::array 啦 Eigen::array<int, 2> new_shape{3, 2}; auto b = a.reshape(new_shape); std::cout << b << std::endl; -0.167619 1.49612 0.238028 -0.212672 0.884384 -0.807312 ...

注意是交换(改变内存顺序)而不是reshape 实现# torch.tensor中内置了permute方法实现快速交换 Eigen::Tensor中实现相同操作需要一点技巧 例如,将一个1x2x3的tensor排列为3x1x2 那么对应t1[0,1,1] == t2[1,0,1]则排列生效 代码如下: #include<iostream>#include<unsupported/Eigen/CXX11/Tensor>template<size_...
Eigen 官方代码仅支持二维矩阵,但其他贡献值提供了高维矩阵处理类Tensor。 Tensor 类 Matrix和Array表示二维矩阵,对于任意维度的矩阵可以使用Tensor类(当前最高支持 250 维) 注意:这部分代码是用户提供的,没有获得 Eigen 官方支持,不在官方文档支持的代码包里 ...

However, in order to return these filtered data Z^3,eigen into the original image space we need to use 2D transform (8) and, thus again to reshape 3D data into 2D transform space. HySime, SVD based algorithm, solves the following problems: estimation of noise and noise covariance matrix ...

Tensor的reshape操作 Tensor的堆叠(stack)操作 平常中我们使用Eigen::MatrixXd二维矩阵。 Eigen的三维张量正处于开发中,在unsupported文件夹下,还没有放到正式代码中。 Eigen::Tensor来定义 IMPORTANT NOTE: The current developement version of Eigen (post-3.2) supports Tensors. This support is experimental and a...
In the case of broadcast, the compiler emits the error "no type named 'Dimensions' in 'Eigen::TensorBroadcastingOp<const std::array<int, 1>, const Eigen::Tensor<double, 1>>'" Steps to reproduce Create a tensor apply a slice/reshape/broadcast (possibly others as well) operation to the ...
