Eigen库中进行矩阵间的变换 表示旋转,在使用四元数进行旋转变换之前需要对四元数进行归一化。旋转向量V ---也称:轴角,由一个旋转轴向量和旋转角组成。旋转轴向量需要标准化为单位向量。欧拉角(Vector3d) ---常用于飞机等人机交互的界面,不常用于SLAM中。在eigen库中,其常用轴角来进行模拟X,Y,Z轴的旋转情况。
This can then be used to find the eigen values and hence the principal components from the images. You may refer to the following MATLAB code for more understanding: ThemeCopy % Load face images into a matrix (here X) where each column is a flattened image vector imageDir = '....
the data set (hence eigenVector(:,2)*x) to the eigenvector of the highest-value eigenvalue. I think smth is wrong with this approach, I get somthing like inverse of the dataset (figure (2)). I multiply the k=1 dimension (eigenvector) with the dataset (w2=eigenVector(:,2)'.*x...

If we rearrange the eigenvalue problem into the form given by (2.41), that is, (B−λI)x=0 then the eigenvalues are the roots of |A−λI|=0. We can find these roots symbolically in Matlab thus: >> syms lambda >> D = A-lambda*sym(eye(5)); >> det(D) ans = -lambda^...
