Cynopolis	b6a649bad9	Added an SVD passthrough to matrix.cpp	2026-08-26 13:07:49 -04:00
Cynopolis	c2f5520664	Got rid of unused function warnings	2026-08-26 12:23:03 -04:00
Cynopolis	c9a9492fcf	Add QR eigen library: implicit Wilkinson-shifted QR for symmetric matrices ... - src/QR.hpp / src/QR.cpp: fully templated QR::EigenQR (N >= 2), no heap allocation (3*N^2 float working buffers on stack). Givens tridiagonalization (bottom-up) + implicit Wilkinson-shifted QR with bulge chasing, relative deflation, exact-zero peeling, closed-form 2x2 termination. - Matrix::EigenQR now delegates to QR::EigenQR (old unshifted body removed); eigenvalues sorted descending, eigenvectors in columns of the output. - unit-tests/qr-build-blocks-tests.cpp: 8 building-block test cases (215 assertions) with scipy/numpy references. - unit-tests/qr-reference-values.py: numpy/scipy reference generator mirroring every building block and the full pipeline (eigh, n=3..8). - CMake: new 'qr' static library; Matrix links against it; qr-build-blocks-tests target enabled.	2026-08-25 14:02:56 -04:00
Cynopolis	ab0cea104c	Templatize SVD on N: support any Matrix<R,C> with stack-only buffers ... Replace the fixed 5x5 SVD implementation with template <uint8_t N> building blocks over Matrix<N,N> working buffers (N = max(rows, cols)), removing the 5x5 size limit. Public API (SVD::SVD) is unchanged and the whole path stays heap-free: peak stack is ~11*N^2 floats, budgeted in the SVD.hpp header doc. Fixes found while porting/validating the templated rewrite: - QL.Identity() was a no-op (static factory returns by value); init the Householder accumulators with an explicit diagonal loop - restore the QL column sign-flip in ExtractAndSortSingularValues for negative unsolved W diagonal entries (Householder sign flips) - T = B^T B tridiagonal formula: T[i][i] = d[i]^2 + e[i-1]^2 only (e[i] contributes to T[i+1][i+1], not T[i][i]) - wide-matrix Vt assembly: Vt = QL^T must be filled over the full m x m (m = columns of A), not just the top n x n Tests: - matrix-tests: add large-size instantiation cases beyond the old limit (tall 7x5 N=7, square 6x6 N=6, wide 5x8 N=8 transpose path with full orthogonal 8x8 Vt, tall 6x4 near rank-deficient N=6 deflation path), all checked against numpy/scipy float32 references - svd-build-blocks-tests: adapt Jacobi test to the Matrix<N,N> interface - svd-reference-values.py: add the four new reference matrices	2026-08-20 10:22:49 -04:00
Cynopolis	f8221dd9db	Add 5x5 SVD end-to-end tests (scipy references) ... - Full-rank random 5x5 (cond ~11.5) - Rank-deficient 5x5 (exact rank 3, noise-level tail sigmas) - Wide dynamic range 5x5 (cond ~9000, diagonal decay 50 -> 1e-3) - Symmetric indefinite 5x5 (sigma = |eigenvalues|)	2026-08-19 15:42:15 -04:00
Cynopolis	ac4bef88fc	Fix SVD pipeline bugs; extract and unit-test bidiagonal block solvers ... - Snapshot bidiagonal block before solving (W overwrite corrupted Ublock) - Wide-matrix QL row extent fix (rowsQL = n when transposed) - Vt output copy bound j<columns (was OOB write clobbering caller sigma) - Rank-deficient blocks: residual singular values sigma_i = ||B*v_i|| instead of sqrt(eigs of B*B) (condition-number squaring); Gram-Schmidt orthonormalization of U columns with rank-deficiency completion - JacobiEigenSymmetric: return signed eigenvalues (removed fabsf) - Fix 28 WithinRel(0.0f,.) matcher misuse -> WithinAbs in matrix-tests - New unit tests: SolveBidiagonalBlock2x2 (7 scipy-referenced cases), JacobiEigenSymmetric (3 cases), DeflateBidiagonal/BidiagonalIsDiagonal	2026-08-19 14:05:44 -04:00
