原文:使用Eigen实现四元数、欧拉角、旋转矩阵、旋转向量之间的转换 Vector3.normalized的特点是当前向量是不改变的并且返回一个新的规范化的向量; Vector3.Normalize的特点是改变当前向量,也就是当前向量长度是1 一、旋转向量 1.1 初始化旋转向量 旋转角为alpha(顺时针),旋转轴为(x,y,z) Eigen::AngleAxisd ...
const Eigen::Vector3d &angular_delta, Eigen::Matrix3d &R_curr, Eigen::Matrix3d &R_prev) { // magnitude: double angular_delta_mag = angular_delta.norm; // direction: Eigen::Vector3d angular_delta_dir = angular_delta.normalized; // build delta q: double angular_delta_cos = cos(angular...
Appendix B: Normalized factors The integrals below are instrumental in the Gram–Schmidt orthogonalization process and in determining the eigenfunctions with zero eigenvalues of the linearized collision operator, $$\begin{aligned} V_{i,j}=\int \textrm{dP}f_{eq}(p){\tilde{\varphi }}_i \tau ...
The RG time t is normalized such that \(t=0\) coincides with the transition scale. We can see that for increasing values of \(g_\Lambda \), and thus \(\Lambda _{{\textrm{QCD}}}/\Lambda _\textrm{F}\rightarrow 1\), the running of \(\eta _{\phi }/g^2\) levels out, ...
orientation_ = (orientation_ * rotation).normalized(); // 更新重力方向。对2D来说,不会改变gravity_vector_,仍是初始值(0, 0, 1)。 gravity_vector_ = rotation.conjugate() * gravity_vector_; // 更新时间 time_ = time; } imu_angular_velocity_类型是Eigen::Vector3d,但它其实是个旋转向量。对...
Using the laser's linear intensity modulation (I 1), the magnitude of the 1f WMS signal (R 1f ) was normalized, producing R 1f / I 1. The value R 1f / I 1 remains unaffected by significant fluctuations in R 1f itself, resulting from the fluctuations in the received light's intensity...
(bottom row) in different cell types. Red arrows indicate the cross-shaped pattern extending from the CO-DSBs in preleptotene and leptotene. The observed Hi-C interaction frequencies are normalized using expected interaction frequencies at each genomic distance (Obs/Exp). Bin size, 10 kb.bBox...
链接:https://github.com/theflofly/dnn_tensorflow_cpp/blob/master/normalized_car_features.csv 要定义一个张量,我们需要它的类型和形状。在data_set对象中,x数据以平坦(flat)的方式保存,所以我们要将尺寸缩减成3(每辆车有3个特征)。然后,我们正在使用std::copy_n将数据从data_set对象复制到张量(Eigen::Tens...
In Fig. 2, we present the ηc-meson mass shift, Δmηc, as a function of the nuclear matter density, ρB, normalized to ρ0, for four values of the cutoff parameter ΛD. As can be seen from the figure, the effect of the in-medium D and ⁎D⁎ mass change is to shift the...
