4.4.010 May 2018 23:53 major feature: This major release improves compatibility with Matlab and contains many new and improved functions. A list of important user-visible changes is available by selecting the Release Notes item in the News menu of the GUI or by typing news at the Octave command prompt.
4.0.029 May 2015 16:25 major feature: A graphical user interface is now the default when running Octave interactively. Octave now uses OpenGL graphics with Qt widgets by default. A new syntax for object oriented programming termed classdef has been introduced. New audio functions and classes. Optional stricter Matlab compatibility for ranges, diagonal matrices, and permutation matrices. The preferences do_braindead_shortcircuit_evaluation, allow_noninteger_range_as_index ares now enabled by default. The "backtrace" warning option is now enabled by default. The nextpow2 function behaviour has been changed for vector inputs. polyeig now returns a row vector of eigenvalues rather than a matrix with the eigenvalues on the diagonal. Interpolation function changes for Matlab compatibility The delaunay function has been extended to accept 3-D inputs. The hyperbolic function acosh now returns values with a phase in the range -pi/2, +pi/2. strfind changes when using empty pattern ("") for Matlab compatibility. Integer formats used in the printf family of functions now work for 64-bit integers. The functions intersect, setdiff, setxor, and union now return a column vector as output unless the input was a row vector. The inpolygon function now returns true for points that are within the polygon OR on it's edge. Qt and FLTK graphics toolkits now support offscreen rendering on Linux. Z-order stacking issues with patches, grid lines, and line object plot markers for on screen display and printing have all been resolved. The patch graphic object has been overhauled. linkprop has been completely re-coded for performance and Matlab compatibility. isprime has been extended to operate on negative and complex inputs. xor has been extended to accept more than two arguments in which case it performs cumulative XOR reduction. The following functions now support N-dimensional arrays: fliplr, flipud, rot90, rectint.
3.8.213 Aug 2014 20:17 minor bugfix: This release adds multiple bugfixes. It also improves the accuracy of range/scalar arithmetic, uses the gnulib log2 modules, allows loading mat5 files generated from R and Python.
