GAMS Module LIN_ALG in C++


LIN_ALG

 
C++ classes and procedures for numerical mathematics. Includes matrix and
vector operations, multivariate optimization, one-dimensional root finding
and function minimization, singular value decomposition, and interpolation
over a grid. Uses "lazy matrices" to provide recipes for constructing matrices,
in order to avoid copying large matrices to temporary storage. (Developed by Oleg
Kiselyov.).
 
Classes  :  D1 .    Elementary vector and matrix operations
            D2a1 .  Solution of systems of linear equations, including matrix
                  inverses, and LU and related factorizations (general real
                  nonsymmetric matrices)
            D3a1 .  Determinants of general real nonsymmetric matrices
            D6 .    Singular value decomposition (SVD)
            D9a1 .  Least squares (L-2) solution of singular, overdetermined
                  or underdetermined systems of linear equations without
                  constraints
            E2a .   Interpolation of gridded multivariate data
            F1b .   Solution of single general nonlinear equations
            G1a1a . Unconstrained optimization of a smooth univariate
                  function, user provides no derivatives
            G1b1a . Unconstrained optimization of a smooth multivariate
                  function, user provides no derivatives
