* test * when performing a forward transformation as part of a simplex step, store "w" for later use when the basis is being updated * find the index of a row in the permutation matrix * more work on pushEtaMatrix(): update the _A matrices according to the new eta matrix. * refactoring: we know that always R=invQ, so just compute it once (when Q) is changed and use it afterwards. Eliminated the R terminology. * use Q, not R * update the factorization when an eta matrix is pushed * small bug fix * done working on pushEtaMatrix, test now passes. * store and restore operations for the new FT basis * added functionality for computing the explicit basis from an FT factorization * keep track of the availability of the explicit basis * dumping functionality * unit test + bug fix for explicit basis computation * initial work on basis inversion using FT factorization * bug fix * todo * removed a too-strong assertion * use FT by default. Bug fix. All unit tests now pass * get rid of the concept of "storedW" add Duligur's fix for cost function resizing * bug fixes and optimizations in BTRAN and FTRAN * optimizations * bug fix * comment * minor * Switching to a non-fixed number of AlmostIdentityMatrices * bug fix in LU factorization * a test for comparing the two factorizations * git ignore * refactorize when the number of A matrices exceeds a threshold * undo a couple of changes before merge * fix broken test * allocate work memory once-and-for-all
