(You can search for basic matrix multiplication rules by yourself) Example: Calculates the value of MOD 1000000007 of the nth term of the Fibonacci series, n AnalysisThe recurrence formula of the Fibonacci series is F (n) = f (n-1) + f (n-2), and the time complexity of F (n) is O (n ), the data range in the question is obviously unacceptable. Obviously, we need a logarithm-level algorithm. Since F (n) = 1

This problem is the basis of dynamic planning and discussed in the introduction to algorithms. Here is a brief description. Assume that there is a matrix that requires multiplication. But we know that matrix multiplication satisfies the combination law first. So we can perform mult
The multiplication of matrices has many functions in the program. You can use matrix concatenation to solve the problem that you encountered two days ago. It took a while to understand why it was the first contact. Here is a summary. First, Using matrix concatenationBenefits: Can be implementedQuick computing. Second, How to convert the problem into the form of

Here, we construct n + 1-dimensional vectors for N numbers to facilitate subsequent 'G' operations. Each operation is represented in a matrix. Here, matrix A is (n + 1, n + 1) and initialized as a matrix of units. The 'G' num operation increases the number of num
