An Introduction to Numerical Analysis
Oxford's standard undergraduate text derives and proves the core algorithms: bisection and Newton iteration, Gaussian elimination, polynomial interpolation, orthogonal polynomials, Gaussian quadrature, initial and boundary value problems for ordinary differential equations, and finite elements, with error and stability analysis throughout.
Numerical Linear Algebra
Trefethen and Bau's forty short lectures on matrix computation, starting from the SVD and QR factorisation and building through conditioning, stability, direct solvers, eigenvalue algorithms and iterative methods such as Arnoldi and conjugate gradients.
