WebAug 6, 2024 · The most time consuming part of the code is the multiplication of two matrices A*B, where A is binary (only 0 or 1 entries) and B is a double matrix. The size of the matrices isn't that large, it's only time consuming because its in the inner loop of some iteration and thus is performed 100k upto a million times. WebMay 26, 2024 · You do not need to fully expand your matrix to do bitwise "multiplication" on it. You want to treat A as a 4x8 matrix of bits and x as an 8-element vector of bits. A row multiplication yields 1 for the bits that are on in both A and x and 0 if either bit is 0. This is equivalent to applying bitwise and ( & ):

WebSep 17, 2024 · The product of a matrix A by a vector x will be the linear combination of the columns of A using the components of x as weights. If A is an m × n matrix, then x must be an n -dimensional vector, and the product Ax will be an m -dimensional vector. If. A = [v1 v2 … vn], x = [ c1 c2 ⋮ cn], then. Ax = c1v1 + c2v2 + …cnvn. WebA square matrix is any matrix whose size (or dimension) is n n(i.e. it has the same number of rows as columns.) In a square matrix the diagonal that starts in the upper left and ends in the lower right is often called the main diagonal. The zero matrix is a matrix all of whose entries are zeroes. The identity matrix is a square n nmatrix, denoted I
