Zazzle is an American online marketplace that allows designers and customers to create their own products with independent manufacturers (clothing, posters, etc.), as well as use images from participating companies. Zazzle has partnered with many brands to amass a collection of digital images from companies like Disney, Warner Brothers and NCAA ...
Linear subspace. One-dimensional subspaces in the two-dimensional vector space over the finite field F5. The origin (0, 0), marked with green circles, belongs to any of six 1-subspaces, while each of 24 remaining points belongs to exactly one; a property which holds for 1-subspaces over any field and in all dimensions.
Cramer's rule. In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution. It expresses the solution in terms of the determinants of the (square) coefficient matrix and of matrices obtained from it by replacing one ...
Linear form. In mathematics, a linear form (also known as a linear functional, [ 1] a one-form, or a covector) is a linear map [ nb 1] from a vector space to its field of scalars (often, the real numbers or the complex numbers ). If V is a vector space over a field k, the set of all linear functionals from V to k is itself a vector space over k ...
Given a real matrix M and vector q, the linear complementarity problem LCP ( q, M) seeks vectors z and w which satisfy the following constraints: (that is, each component of these two vectors is non-negative) or equivalently This is the complementarity condition, since it implies that, for all , at most one of and can be positive.
Outline of linear algebra. This is an outline of topics related to linear algebra, the branch of mathematics concerning linear equations and linear maps and their representations in vector spaces and through matrices.
Linear least squares ( LLS) is the least squares approximation of linear functions to data. It is a set of formulations for solving statistical problems involved in linear regression, including variants for ordinary (unweighted), weighted, and generalized (correlated) residuals . Numerical methods for linear least squares include inverting the ...
The intersection point is the solution. In mathematics, a system of linear equations (or linear system) is a collection of two or more linear equations involving the same variables. [ 1] [ 2] For example, is a system of three equations in the three variables x, y, z. A solution to a linear system is an assignment of values to the variables such ...
