INTLAB
INTLAB (INTerval LABoratory) is an interval arithmetic library[1][2][3][4] using MATLAB. It is 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[5] and INTSOLVER,.[6] It was also used to solve some problems in the Hundred-dollar, Hundred-digit Challenge problems.[7]

Features
[change | change source]INTLAB can help users to solve the following mathematical/numerical problems with interval arithmetic.
- Numerical linear algebra[1][2][3][4] (Not only solving matrix systems or eigenvalue problems, INTLAB can handle the least squares, Hessian matrix,[1][3] and verify the positive definiteness of a given matrix[8])
- root-finding algorithm[1][3][4]
- Affine arithmetic[1][9]
- Solving ODEs rigorously (This feature includes external tools such as the AWA toolbox and the Taylor model toolbox)[1][3][10]
- Automatic differentiation[1][3][4][11]
- Numerical integration[1][3]
- Fast Fourier transform[1]
- Rigorously compute the gamma function[12]
