Numerical Utilities for MATLAB

Summary

Vectorized and other convenience functions. Licensed under the 2-clause BSD.

Description

These functions were developed over time to support my research. The vectorized ones aim to make vector field codes brief, coordinate-free, clear and readable. The more interesting are:

• vectorized meshgrid: generate and manipulate grids (parallelepiped or polar), handy for computing functions accepting column vectors as arguments and vectorized surface plotting, previously published here
• normvec: vectorized normalization, previously published here
• cell extrema, previously published here
• anti-eigenvalues
• 3d matrix multiplication using multiprod
• Cartesian, polar coordinate helpers
• proximity_components finds the connected components of a point set, given some distance threshold, requires vdistance (renamed) and scomponents
• vremnan to remove by row or column if they contain NaN, vector-oriented function inspired by remnan
• omit to exclude a value, e.g., for taking omitted products

Installation

Add the directory tree of this package to your MATLAB path. Some functions have fex dependencies. No dependency is OS-specific.
