代码说明:

  采用有限单元法计算平面刚架自振频率,可生成单刚、单元质量阵并组成总刚、总质量矩阵,并绘图显示。(Plane frame using the finite element method to calculate the natural frequency can be generated just a single unit consisting of the total mass matrix and just total mass matrix, and graphics.)

    Eigenfaces: PCA tends to find a p-dimensional subspace whose basis vectors correspond to the maximum variance direction in the original image space (p  N). We called the new subspace defined by basis vectors “face space”. First, all training faces are projected onto the face space to find a set of weights that describes the contribution of each vector. Then we project all testing faces onto the face space to obtain a set of weights. Finally, we identify the face by comparing a set of weights for the testing face to sets of weights of training faces.
