matrix-vector multiplication
... The nal storage scheme we consider is for skyline matrices, which are also called variable band or pro le matrices (see Du , Erisman and Reid [80]). It is mostly of importance in direct solution methods, but it can be used for handling the diagonal blocks in block matrix factorization methods. A ma ...

In mathematics, a matrix (plural matrices) is a rectangular table of
... Here and in the sequel we identify Rn with the set of "columns" or n-by-1 matrices. For every linear map f : Rn → Rm there exists a unique m-by-n matrix A such that f(x) = Ax for all x in Rn. We say that the matrix A "represents" the linear map f. Now if the k-by-m ...

Recitation Notes Spring 16, 21-241: Matrices and Linear Transformations February 9, 2016
... Additional Notes 1. Let u, v be vectors in Rn . Note the difference between u · v and uT v even though they evaluate to the same ’value’. 2. Matrix addition is defined on matrices of the same size. 3. Matrix multiplication is defined when the number of columns of the first matrix is the same as the ...
