There are no new features. +This is a bug-fixing release. There are only a few new features: + + * If the argument to eig() is symmetric, Octave uses the specialized + Lapack subroutine for symmetric matrices for a significant + increase in performance. + + * It is now possible to use the mkoctfile script to create .oct + files from multiple source and object files. Octave is a high-level interactive language primarily intended for numerical computations. It is mostly compatible with MATLAB.
