At its core, matrix vector multiplication is the process of combining two mathematical objects – a matrix and a vector – to produce another vector. A matrix is a two-dimensional array of numbers, while a vector is a one-dimensional array. When you multiply a matrix by a vector, the result is a new vector whose components are the dot products of the corresponding rows of the matrix with the vector. For example, consider a matrix A = [1, 2; 3, 4] and a vector v = [5, 6]. The result of multiplying A by v would be a new vector [19, 43].
