You can factorize the matrix using LU or LDLT factorization algorithm. inverse of a diagonal matrix (D) is really simple. To find the inverse of L, which is a lower triangular matrix, you can find the answer in this link.www.mcs.csueastbay.edu/~malek/TeX/Triangle.pdfSince (A T )-1 = (A-1 )T for all matrix, you'll just have to find inverse of L and D.
additive identity matrix by one.
It would be no different. Matrix addition is Abelian or commutative. Matrix mutiplication is not.
The time complexity of the Strassen algorithm for matrix multiplication is O(n2.81).

A fast-transpose is a computer algorithm that quickly transposes a sparse matrix using a relatively small amount of memory. Using arrays normally to record a sparse matrix uses up a lot of memory since many of the matrix's values are zero. In addition, using the normal transpose algorithm to transpose this matrix will take O(cols*elements) amount of time. The fast-transpose algorithm only uses a little memory to record the matrix and takes only O(cols+elements) amount of time, which is efficient considering the number of elements equals cols*rows.
The algorithm to find the longest increasing path in a matrix is called the Longest Increasing Path in a Matrix (LIP) algorithm. It involves using dynamic programming to recursively search for the longest increasing path starting from each cell in the matrix. The algorithm keeps track of the length of the longest increasing path found so far and updates it as it explores different paths.
Matrix addition is commutative if the elements in the matrices are themselves commutative.Matrix multiplication is not commutative.
The RANSAC algorithm can be used to estimate a homography matrix by iteratively selecting random sets of corresponding points in two images and calculating the homography matrix for each set. The set with the most inliers (points that fit well with the estimated homography) is then chosen as the best estimate. This helps in robustly matching corresponding points between the two images.

Yes. Matrix addition is commutative.

That is non-commutativity. Matrix multiplication is non-commutative although addition still is.
The definition of "standard algorithm" is that it is a mathematical method used to solve problems such as addition, substraction, division, and multiplication.
