INTLAB facts for kids
INTLAB (INTerval LABoratory) is an interval arithmetic library using MATLAB and GNU Octave, available in Windows and Linux, macOS. It was developed by S.M. Rump from Hamburg University of Technology. INTLAB was used to develop other MATLAB-based libraries such as VERSOFT and INTSOLVER, and it was used to solve some problems in the Hundred-dollar, Hundred-digit Challenge problems.

Functionality
INTLAB can help users to solve the following mathematical/numerical problems with interval arithmetic.
- Numerical linear algebra (Not only solving matrix systems or eigenvalue problems, INTLAB can handle the least squares, Hessian matrix, and verify the positive definiteness of a given matrix)
- root-finding algorithm
- Affine arithmetic
- Solving ODEs rigorously (This feature includes external tools such as the AWA toolbox and the Taylor model toolbox)
- Automatic differentiation
- Numerical integration
- Fast Fourier transform
- Rigorously compute the gamma function
