# Numerical Analysis Topics

**Abstract Program**- A mathematical program defined on an abstract vector space.
**Active Constraint**- An inequality constraint that holds with equality (at a point).
**Algebraic Multiplicity of an Eigenvalue**- The algebraic multiplicity of an eigenvalue c of a matrix A is the number of times the factor (t-c) occurs in the characteristic polynomial of A.
**Complementary Slackness**- Condition that two non-negative vectors are orthogonal.
**Complexity**- Measure of computer time or space to solve a problem by an algorithm as a function of the problem′s dimensions.
**Dispersion Model**- A computerized set of mathematical equations that uses emissions and meteorological information to simulate the behavior and movement of air pollutants in the atmosphere.
**Least-Squares Solution of a Linear System**- A least-squares solution to a system of linear equations Ax = b is a vector x that minimizes the length of the vector Ax - b.
