where n runs from 0 to infinity, meaning the full matrix is infinite-dimensional. My Questions: 1- How can I define this density matrix in Mathematica? 2- Is there a more efficient way to represent it symbolically? 3-What is the best approach to compute its eigenvalues numerically?
NOTE If you need to define a special rule for an object file, put the rule for the object file just above the rule that builds the executable. If several executables use the same object file, put the object rule above all of the executable rules. 注意 如果需要为对象文件定义特殊规则,请将...
Page 2 Its like if you want to be a good pianist, you have to do a lot of scales and a lot of practice, and a lot of that is kind of boring, its work. But you need to do that before you can really be very expressive and really play beautiful music. You have to go through ...
MATLAB has two ways to define a class. With the first way, you can put all of the class definition in a single file with the name of the class as the filename. Then within the file, you can use the classdef keyword to define the properties and methods that belong to the class. Wi...

the eigenvalues equal the variances of the covariance matrix and the eigenvectors are equal to the definition of the x-axis and y-axis. In the case of arbitrary correlated data, the eigenvectors represent the direction of the largest spread of the data, whereas the eigenvalues define how large...
