WebTo multiply two matrices together the inner dimensions of the matrices shoud match. For example, given two matrices A and B, where A is a m x p matrix and B is a p x n matrix, you can multiply them together to get a new m x n matrix C, where each element of C is the dot product of a row in A and a column in B. WebExample 1: Determine the dimension of, and a basis for, the row space of the matrix A sequence of elementary row operations reduces this matrix to the echelon matrix The rank of B is 3, so dim RS(B) = 3. A basis for RS(B) consists of the nonzero rows in the reduced matrix: Another basis for RS(B), one consisting of some of the original rows of ...
