6 Summary of important user-visible changes for version 4.4 (2018-04-30): |
|
|
7 ---------------------------------------------------------------------- |
|
|
8 |
|
|
9 ** A graphical Variable Editor has been added to the GUI interface. |
|
|
10 It uses a spreadsheet-like interface for quick, intuitive editing |
|
|
11 of variables. The Variable Editor is launched by double-clicking |
|
|
12 on a variable name in the Workspace Window or by typing |
|
|
13 "openvar VARIABLE_NAME" in the Command Window. |
|
|
14 |
|
|
15 ** On systems with 64-bit pointers, --enable-64 is now the default and |
|
|
16 Octave always uses 64-bit indexing. However, if the configure |
|
|
17 script determines that the BLAS library uses 32-bit integers, then |
|
|
18 operations using the following libraries are limited to arrays with |
|
|
19 dimensions that are smaller than 2^31 elements: |
|
|
20 |
|
|
21 BLAS LAPACK QRUPDATE SuiteSparse ARPACK |
|
|
22 |
|
|
23 Additionally, the following libraries use "int" internally, so |
|
|
24 maximum problem sizes are always limited: |
|
|
25 |
|
|
26 glpk Qhull |
|
|
27 |
|
|
28 ** The octave command no longer starts the GUI by default. Most users |
|
|
29 starting Octave from a shell were expecting the command line |
|
|
30 interface, and desktop launchers already required the `--force-gui' |
|
|
31 option. With this change, desktop launchers should be modified to |
|
|
32 use the new option `--gui'. The previous `--force-gui' option will |
|
|
33 continue to work, and maps to `--gui', but it will be removed in |
|
|
34 Octave 6. |
|
|
35 |
|
|
36 ** A known bug in Qt (https://bugreports.qt.io/browse/QTBUG-55357) is |
|
|
37 addressed by limiting GUI sub-panel relocation capabilities for Qt |
|
|
38 versions in the range >= 5.6.1 and < 5.7.1. However, this may not |
|
|
39 thoroughly avoid issues on all platforms. |
|
|
40 |
|
|
41 ** A new container data type--containers.Map--is available. Map is a |
|
|
42 key/value storage container (a.k.a, a hash) that efficiently allows |
|
|
43 storing and retrieving values by name, rather than by position which |
|
|
44 is how arrays work. |
|
|
45 |
|
|
46 ** The bareword "import" is now recognized in scripts and functions. |
|
|
47 However, the functionality to import functions and classes from |
|
|
48 other namespaces into the local scope has not yet been implemented. |
|
|
49 Attempting to use "import" will provoke an error message. |
|
|
50 |
|
|
51 ** hex2num and num2hex now work for integer and char types and num2hex |
|
|
52 may optionally return a cell array of strings instead of a character |
|
|
53 array. If given a cell array of strings, hex2num now returns a |
|
|
54 numeric array of the same size as the input cell array. Previously, |
|
|
55 hex2num would accept a cell array of strings of arbitrary dimension |
|
|
56 but would always return a column vector. |
|
|
57 |
|
|
58 ** New special functions cosint, sinint, and gammaincinv have been added. |
|
|
59 |
|
|
60 ** Special functions in Octave have been rewritten for larger input |
|
|
61 domains, better accuracy, and additional options. |
|
|
62 * gammainc now accepts negative real values for X. |
|
|
63 * improved accuracy for gammainc, betainc, betaincinv, expint. |
|
|
64 * gammainc has new options "scaledlower" and "scaledupper". |
|
|
65 * betainc, betaincinv have new option "upper". |
|
|
66 |
|
|
67 ** The "names" option used in regular expressions now returns a struct |
|
|
68 array, rather than a struct with a cell array for each field. This |
|
|
69 change was made for Matlab compatibility. |
|
|
70 |
|
|
71 ** The quadcc function now uses both absolute tolerance and relative |
|
|
72 tolerance to determine the stopping criteria for an integration. |
|
|
73 To be compatible with other quadXXX functions, such as quadgk, the |
|
|
74 calling syntax has changed to |
|
|
75 |
|
|
76 quadcc (f, a, b, [AbsTol, [RelTol]]) |
|
|
77 |
|
|
78 To update existing code, change instances of RelTol to [0, RelTol]. |
|
|
79 |
|
|
80 quadcc (f, a, b, tol) => quadcc (f, a, b, [0, tol]) |
|
|
81 |
|
|
82 A warning that a single tolerance input is now interpreted as an |
|
|
83 absolute tolerance will be issued in Octave versions 4.4 and 5, |
|
|
84 after which it will be removed. The warning has ID |
|
|
85 "Octave:quadcc:RelTol-conversion" and can be disabled with |
|
|
86 |
|
|
87 warning ("off", "Octave:quadcc:RelTol-conversion") |
|
|
88 |
|
|
89 ** The qr function now returns a standard factorization unless |
|
|
90 explicitly instructed to perform an economy factorization by using a |
|
|
91 final argument of 0. |
|
|
92 |
|
|
93 ** The Qt graphics toolkit now supports offscreen printing without osmesa |
|
|
94 if Octave was built with Qt >= 5.1. |
|
|
95 |
|
|
96 ** The built-in pager for display of large data is now disabled by |
|
|
97 default. To re-enable it for every Octave session add the following |
|
|
98 to your .octaverc file: |
|
|
99 |
|
|
100 more on; |
|
|
101 |
|
|
102 ** The FLTK toolkit is no longer prioritized for development. The |
|
|
103 number of Octave Maintainers is too small to support three different |
|
|
104 graphic toolkits. New development will target the Qt toolkit. |
|
|
105 While no longer prioritized, the FLTK toolkit is not deprecated and |
|
|
106 there is no schedule for its removal. |
|
|
107 |
|
|
108 ** The graphic object property "PickableParts" has been implemented |
|
|
109 which controls whether an object can accept mouse clicks. |
|
|
110 |
|
|
111 ** The graphic object property "Interruptible" has been fully |
|
|
112 implemented which controls whether a running callback function can |
|
|
113 be interrupted by another callback function. |
|
|
114 |
|
|
115 ** The graphic object property "HitTest" has been updated to be fully |
|
|
116 compatible with Matlab. |
|
|
117 |
|
|
118 ** Text objects now implement the properties "BackgroundColor", |
|
|
119 "EdgeColor", "LineStyle", "LineWidth", and "Margin". |
|
|
120 |
|
|
121 ** An initial implementation of alpha transparency has been made for |
|
|
122 patch and surface objects. Printing to svg and pdf is supported. |
|
|
123 |
|
|
124 ** ishandle now returns true for both graphics handle objects and |
|
|
125 Java objects. The latter change was made for Matlab compatibility. |
|
|
126 Use ishghandle or isgraphics if it is important not to include Java |
|
|
127 objects. |
|
|
128 |
|
|
129 ** The pkg command now accepts a URL as an argument, allowing a valid |
|
|
130 Octave package to be installed from any remote host with one command, |
|
|
131 for example |
|
|
132 |
|
|
133 pkg install https://example.org/download/example-package.tar.gz |
|
|
134 |
|
|
135 ** The following statistical functions have been moved from core |
|
|
136 Octave to the statistics package available from Octave Forge. |
