Updated: 2016 JULIt is known from the QR method that most of the eigenvalues of Matrix $a$ need to be tri-diagonalization first (see Xu Xiaofang's textbook for detailed methods.) An example of an outer chain here), i.e.$$ T=q^taq $$That is, finding the orthogonal matrix $q$ makes the $t$ a three-diagonal matrix. However, if the $a$ is a large sparse
"Transformation matrix" uses "affine transformations affine transformation" properties:
The "affinine transform" refers to the coordinate point that changes the relative distance in the space while the coordinate points are in the same line (surface. This means that the plane of the coordinate point does not change, and the original parallel straight line is still parallel, but the distance between the coordinate point and the coordinate point may cha

So that c = A * a, then C (I, j) = Σ a (I, k) * a (K, J ), in fact, it is equal to the number of paths from point I to Point J passing through two sides (enumeration K is a vertex ). Similarly, column J of row I of C * A indicates the number of paths passing through three ed

Description:
Any input of two matrices lower than 9 must determine whether the second is the first rotation matrix. If yes, the output rotation angle (0, 90, 180, 270). If not, output-1.You must first enter the matrix order, and then enter two matrices.
Question:
Find the sum of K * I + B in Fibonacci.
Train of Thought Analysis:
Defines the matrix of the Fibonacci series
F (n) is the nth entry of Fibonacci
F (n) = f (n + 1)
F (N)
Then we can know the matrix.
A = 1 1
1 0
Make F (n) = A * F (n + 1)
Then we simplify the final answer.
Sum = F (B) + f (K + B) + F (2 * k + B )....
Sum = F (B) + A ^ k f (B) + A ^ 2 k f (B ).....
Sum = (E + A ^ K + A ^ 2 k...)
MAX7219 lattice module can be used with three data lines to achieve 8*8 led lattice control, and do not need to participate in the scanning of single-chip computer, the use is very convenient. More importantly, it supports the use of modular cascade, without increasing the number of IO, the implementation of multi-module control. Therefore, in the large-screen meter, the use of 3 MAX7219 lattice modules into a 8*24 lattice screen.The use of dot matrix
