计算转子各阶临界转速。考虑了陀螺力矩。用FEM法。(Calculation of the rotor of the first critical speed. Consider the gyroscopic moment. With the FEM method.)

经典谱估计方法的MATLAB分析,主要是周期图法及其改进(MATLAB classical analysis of spectral estimation method, the main improvement is the periodogram and)

利用隐式QR方法求一个实矩阵全部特征值和特征向量的通用子程序。(use QR method is seeking a full matrix eigenvalue and eigenvectors of generic subroutine.)

详细地介绍了各类常见的优化算法，以及其相应的matlab程序。(Detailed description of the common optimization algorithms, as well as the corresponding matlab program.)

在图像精度评价中，主要用于比较分类结果和实际测得值，可以把分类结果的精度显示在一个混淆矩阵里面。混淆矩阵是通过将每个实测像元的位置和分类与分类图像中的相应位置和分类像比较计算的。(In the image to uate the accuracy, mainly for comparison of classification results and the actual measured value, the accuracy of the classification results are displayed in a confusion matrix inside. The confusion matrix is measured by each pixel position and image classification and classification in the appropriate location and classified as comparative calculations.)
