Let us discuss how to multiply a matrix by another matrix, its algorithm, formula, 2×2 and 3×3 matrix multiplication. To multiply a matrix by another matrix we need to follow the rule “DOT … WebT u k = ∑ r = 1 n C r, k v r; this is just the standard process for recovering T u k from its coordinate vector in the k th column of C. It's not really just "matrix times a column", since v r may not be a column vector. It's an element of V, which may or may not be equal to R n. It might be that v r is a polynomial, or some other abstract vector.
