DQED - Bounded, Constrained Least Squares/Nonlinear Equations
DQED can solve, in the least squares sense, systems of linear or nonlinear equations, with bounds or constraints.
Files you may copy include:
dqed.f90, the source code.
dqed_prb.f90, a sample problem.
dqed_prb.inp, input for the sample problem.
dqed_prb.out, sample problem output.
The list of routines includes:
DIFCEN estimates a jacobian using central differences.
DIFFOR estimates a jacobian using forward differences.
IDAMAX finds the index of the vector element of maximum absolute value.
IVOUT prints integer vectors.
DAMAX returns the maximum absolute value of the entries in a vector.
DASUM sums the absolute values of the entries of a vector.
DAXPY adds a constant times one vector to another.
DBOCLS solves a bounded and constrained least squares problem.
DBOLS solves the linear system E*X = F in the least squares sense.
DBOLSM solves E*X = F in the least squares sense with bounds on some X values.
DCOPY copies one vector into another.
DDOT forms the dot product of two vectors.
DGECO factors a double precision matrix and estimates its condition.
DGEFA factors a double precision matrix.
DGESL solves a system factored by DGECO or DGEFA.
DMOUT prints double precision matrices.
DNRM2 computes the Euclidean norm of a vector.
DPCHEK checks the user's jacobian routine.
DQED solves bounded and constrained least squares and nonlinear equations.
DQEDEV evaluates functions being treated by DQED.
DQEDGN ???
DQEDIP ???
DQEDMN ???
DROT applies a plane rotation.
DROTG constructs a Givens plane rotation.
DSCAL scales a vector by a constant.
DSWAP interchanges two vectors.
DVOUT prints double precision vectors.
XERRWV is an error output message routine.
