Theorem 3 … WebWe have gotten some mileage out of partitioning the matrix on the right-hand side of a product. If we partition the matrix on the left-hand side of a product, other opportunities emerge. If A= [a 1 a 2::: a n] 2M m n and x = [x 1 x 2::: x n]T 2 Cn, then Ax = x 1a 1 + x 2a 2 + + x na n: (9) That is, Ax is a linear combination of the columns of A.

In mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, into a collection of smaller matrices. Any matrix may be interpreted as a block matrix in one or more ways, with each interpretation defined by how its rows and columns … WebThe partitioned matrix multiplication follows in similar plication, with “rows diving fashion to the usual matrix multi into columns”. Care nonetheless must be taken to ensure that the submatrices are compatible for multiplication. ...

Webby the second column, or by the third column. Although the Laplace expansion formula for the determinant has been explicitly verified only for a 3 x 3 matrix and only for the first row, it can be proved that the determinant of any n x n matrix is equal to the Laplace expansion by any row or any column.
