矩阵行列式 meaning in Chinese
matrix determinant
Examples
- Two indexes was calculated to estimate the best bands union for color combination , one is optimum index factor ( oif , the sum of standard deviation divided by the sum of correlation coefficient . ) , the other is the determinant of the co - variance matrix . it can be seen from the result that for color combination the original optimal bands were tm 4 , 3 , 7 and tm 4 , 3 , 5 , the best mixed images were mnf1 , br and ndvi
以协方差矩阵行列式值和最佳指数值(组合波段标准差之和除以相关系数之和)为评价标准，得出对于tm原始波段而言，最佳的彩色合成组合是tm4 、 3 、 7和tm4 、 3 、 5 ；综合几种变换图像的彩色合成的最佳组合是mnf1 、 br 、 ndvi 。 - Chapter 2 : using a so - called variance matrix , we studied the propagation and the focusing characteristics of the paraxial light beams . the quantities characterizing the gross features for a paraxial optical beam , such as the beam width , the divergence , the curvature radius of the wavefront , the complex beam parameter q . and the beam quality factor , are related by using variance matrix
第二章：阐述了常数折射率介质中光束的传输和聚焦，建立了表征傍轴光束总的特征的量，如：束宽、衍射发散角、波前曲率半径、复光束参数q与变换矩阵的关系，得到了光束质量因子和变换矩阵行列式的定量关系。 - The singularity analysis of the general 6 dof parallel manipulator is transformed into the optimal issue in the reachable workspace , the square of the determinant of jacobian matrix is selected as the objective function , and the minimal of this objective function is searched by a real - coded genetic algorithm
