👉 Gemmipares is a type of matrix in linear algebra, specifically used to represent sparse matrices. It's often used for numerical computation and optimization tasks where the number of non-zero elements (or rows or columns) in a matrix is much smaller than its dimension. In other words, it's a special kind of matrix that can be efficiently computed using only row vectors or column vectors. For example, if you have a 3x4 matrix with all entries equal to 1 (since there
