gt matrix

A few months ago, I happened to see Meng's blog, and after reading it, unlike a deeper understanding of the matrix. Now let's summarize and share. "According to current international standards, linear algebra is expressed by axiomatic, it is the second generation mathematical model, ..., which brings about teaching difficulties." "In fact, when we started to learn linear algebra, unknowingly entered the" second-generation Mathematical model "category

Problem descriptionThere is a matrix of N * M, where the element is 0, and if it is 0, then the row and the column are set to 0. Space complexity required for O (1)Problem analysisAt first glance this problem is really simple, there is not too much algorithm content.If there is an O (M + N) space, then all of the columns and rows containing 0 can be stored. Then set the 0 individually.Now the requirement is to use the space complexity of O (1), what s

row, using a one-dimensional array of length n to record whether there are 0 in each column, and finally updating the matrix array directly. The requirement of this problem is to use O (1) space, then we can not create a new array, we consider using the first row of the original array of the first column to record the rows of each column is 0.-Scan first Column first, if 0, set the respective flag to True-then the scan removes the entire array of the

(Daily algorithm) LeetCode -- Set Matrix Zeroes (Matrix Set to zero) Given a matrix, if there is a zero element, the row and column of the zero element are set to zero. Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in place. The most intuitive solution is to create a new

In the matrix, there is a kind of very important matrix, that is-----sparse matrix.The so-called sparse matrix, that is, in the matrix, the number of valid data is far less than the number of invalid data (and these data are not ordered in order). Let's start with an example of a sparse

result of a common method may be beyond the range expressed by an integer in C/C ++. At this time, we will use the matrix's quick power. The quick power template for numbers is as follows: // m^n % kint quickpow(int m,int n,int k){ int b = 1; while (n > 0) { if (n 1) b = (b*m)%k; n = n >> 1 ; m = (m*m)%

If a diagonally dominant, that is |aii| >δi, (including row diagonally dominant and column diagonally dominant), then a is not singular. 3. If the n Gaelic Circle 22 of a does not intersect, A has n mutually exclusive eigenvalues, and A is a simple matrix. 4. If the solid phalanx A has k isolated G
