mathlib-fp 2.2.0

Version 2.2.0 is the current published stable release. It combines the 2.1 special-functions scope with the 2.2 nonsymmetric spectral-algebra scope.

Included capabilities

• Bounded real-double Bessel J/Y and modified Bessel I/K functions, Legendre elliptic integrals, real exponential integrals, bounded real Gauss 2F1, and Jacobi elliptic sn/cn/dn.
• Real and complex Hessenberg reductions and Schur factorizations.
• Real-input nonsymmetric eigenvalues and right eigenvectors, with ordering, residual, and bounded convergence diagnostics.
• Real and complex generalized matrix-pencil factors and homogeneous eigenvalues, including infinite eigenvalues when the B matrix is singular.

Each family retains its documented domain, accuracy, convergence, and failure limits. See the 2.2 API reference, dense linear algebra guide, MathBase guide, and changelog.

Qualification status

The release passed checksummed clean-archive qualification on Linux and Windows, including performance, portability, documentation, Lazarus package, and artifact checks. The qualification record links the workflow and its uploaded evidence.
