Tensors

Programs and utility functions using the Symbolic Math Toolbox are provided to analyze vectors and tensors in general curvilinear coordinates. The programs perform the following functions: 1) runcoord plots intersecting coordinate surfaces for typical coordinate systems 2) runmetric computes and... Platforms: Matlab

The program parses Gaussian 98/03 single-point output and draws HFC tensors as ellipsoids on top of the length-based connected molecule. Platforms: Matlab
