Fortran matrix solver.
Nonlinear Equation Solver with Modern Fortran.
Fortran matrix solver (Specification) Summary Subroutine interface for solving a linear system using LU decomposition. Status Description Syntax Arguments Return value Example lstsq - Computes the least squares solution to a linear A community driven standard library for (modern) Fortranpublic interface solve_lu Solves the linear system A ⋅ x = b A x = b for the unknown vector x x from a square matrix A A. Description This interface provides methods for computing the solution of a linear matrix system using a subroutine Aug 28, 2012 · MGMRES is a FORTRAN90 library which applies the restarted Generalized Minimum Residual (GMRES) algorithm to solve a sparse linear system, using compressed row (CR) or sparse triplet (ST) format, by Lili Ju.

Status Features Is object-oriented. To get solution of sparse linear systems: Ax=b, where A is large and sparse, GSS uses adaptive computing technology, which will run both CPU and GPUs to get more performance. Fortran 90 package for solving linear systems of equations of the form A*x = b, where the matrix A is sparse and can be either unsymmetric, symmetric positive definite, or general symmetric. Supported data types include A Fortran 2008 edition of LSQR, a conjugate-gradient type method for solving sparse linear equations and sparse least-squares problems. Can use different methods to solve the linear system: LAPACK routines (dgesv or dgels) for dense systems: If Nonlinear Equation Solver with Modern Fortran. if n=m : use LAPACK dgesv (LU decomposition) if n/=m : use LAPACK dgels (if m>n uses QR factorization, if m<n uses LQ factorization) Arguments solve - Solves a linear matrix equation or a linear system of equations. qhwmlvnkspsuykxnsdclvagsxyopnbcjldlahmmzpshbzhjcexiygzzyxghykofaeavihrrq
