Determinant of partitioned matrix

WebPartitioning plays an important role in sparse matrix technology because many algorithms designed primarily for matrices of numbers can be generalized to operate on matrices … 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 …

Webdoes not depend on the number of 1’s in the partition. We are particularly interested in two special kinds of partitions. Let n be a fixed positive integer. A partition of 2n into exactly n parts is called a type I partition and a partition of 2n having at least n 1’s is called a type II partition. Proposition 1.3. WebBy induction you know that its determinant is det A det B. On your second question: The sign in det( 0 B CB − DA D) = − det(CB − DA)det(B) is not quite true. You are moving each of the n rows of CB − DA past each of the n rows of 0. That's a total of n2 sign changes, so you should get a sign of ( − 1)n2 = ( − 1)n. monitor on wheels

WebMAT-0023: Block Matrix Multiplication. It is often useful to consider matrices whose entries are themselves matrices, called blocks. A matrix viewed in this way is said to be partitioned into blocks. For example, writing a matrix B B in the form.
