... subscripts. For integers i and j, i:j is used to denote a row vector from i to j in steps of 1. • A nonunit stride or step is denoted i:s:j. • Matrix subscripts (1 or greater!) are accessed as A(i,j). • A(p:q,r:s) is a submatrix of A. • A(:,j) is the jth column and A(i,:) is the ith row. • end repre ...

Matrix manipulations
... We say a matrix A ∈ Rn×m is data sparse if we can represent it with far fewer than nm parameters. For example, • Sparse matrices are data sparse – we only need to explicitly know the positions and values of the nonzero elements. • A rank one matrix is data sparse: if we write it as an outer product ...

WHAT IS A POLYNOMIAL? 1. A Construction of the Complex
... the above construction of C may appear ad hoc, what is easier to show is that any field that forms a 2-dimensional vector space over R is field-isomorphic to C. Thus any peculiarities of the construction of C are irrelevant. This handout discusses polynomial algebras in terms similar to this introdu ...
