Solving Linear Inverse Models CRAN Task View: Optimization (http://CRAN.R-project.org/view=Optimization) Functions that (1.) Find the minimum/maximum of a linear or quadratic function: min or max (f(x)), where f(x) = ||Ax-b||^2 or f(x) = sum(ai*xi) subject to equality constraints Ex=f and/or inequality constraints Gx>=h. (2.) Sample an underdetermined- or overdetermined system Ex=f subject to Gx>=h, and if applicable Ax~=b. (3.) Solve a linear system Ax=B for the unknown x. Includes banded and tridiagonal linear systems. The package calls Fortran functions from LINPACK Software Depends: R (>= 2.10), quadprog, lpSolve, MASS Karline Soetaert <karline.soetaert@nioz.nl> Karline Soetaert <karline.soetaert@nioz.nl>, Karel Van den Meersche <k.vdMeersche@nioo.knaw.nl>, Dick van Oevelen <dick.vanoevelen@nioz.nl> GPL (>= 2) 2012-04-19 application/tgz http://CRAN.R-project.org/package=limSolve
