WebUsing 8x8 Binary Matrices as a hash. I had the idea of computing a 64 bit hash of a text string by assigning a unique binary 8x8 matrix to each character, and computing the hashes of larger strings by multiplying the matrices corresponding to the substrings. In this system both addition and multiplication of matrix elements would be modulo 2. WebJun 4, 2024 · Let H be a binary matrix. The null space of H is a single error-correcting code if and only if H does not contain any zero columns and no two columns of H are identical. …

They don't necessarily have same lengths but all of them are proper m x n binary matrices with 0s and 1s as the only values. I want to find the shape similarity of 1s in them. These two matrices have same shape for 1s and (same shape of 0s, of course). What I was doing was calculating the number of 1s in …
WebSep 23, 2024 · A binary matrix is a matrix whose all elements are binary values i.e., 0 or 1. Binary matrix can be also called Boolean matrix, Relational Matrix, Logical matrix.. … WebOne use of matrices over F*2* is integer factorization.If x 2 = y 2 mod n, then x 2 - y 2 = 0 mod n, or n divides (x+y)(x-y). There is a 50% chance that you get a non-trivial factorization of n by considering gcd(x-y,n). There are methods like CFRAC and the Quadratic Sieve where you compute various x*i 2 = yi* mod n, and keep those values for which y*i* …
