29 <h3 class="title">Welcome to Scilab 6.0.1</h3>
31 Scilab 6.0 is a major new release of Scilab, the open source
32 platform for numerical computation.
35 Here is a tour of the changes between Scilab 6.0.0 & 6.0.1.
37 <h2 class="title">Feature Improvements</h2>
39 The console "File => Open a file" menu now allows to open *.xcos *.zcos *.scg or lib
40 files with the proper Scilab component, and other files with the proper OS application.
41 All files were opened in Scinotes and could freeze it.
44 "gcd" and "lcm" of integers now always return a positive result.
47 "cat" has been rewritten. It is now fast and can process heavy arrays at high dimensions.
50 Warnings from "fplot3d1" called without an option were removed.
53 "whereis" has been upgraded:
55 <li>It can now be used for built-in functions.</li>
56 <li>When the same function name is registered in several libraries, "whereis"
57 now returns all of them instead of only the last loaded one.</li>
58 <li>For unregistered user-defined macros, ""script"" is now returned
59 instead of "[]".</li>
63 "mgetl" speed has been improved for files with a lot of lines.
66 "ndgrid(x)" now accepts only one input "x", with by default "y=x".
69 Some functions have been tagged obsolete and will be removed in Scilab 6.1: "nanmin",
70 "nanmax", "xgetech", "lstsize", "eval" & "dgettext" & "denom" & "numer".
72 <h2 class="title">Help pages</h2>
74 Support to "id", "width", "height", "align"
75 and "style" attributes added for the "<imagedata>" tag.
78 Support to "id" attribute added for the "<tr>" tag.
81 Numerous pages have been improved, comprising: "ismatrix", "xget", "xset",
82 "ieee", "evstr", "uigetfont", "uigetdir", "uigetfile",
83 "uiputfile", "cat", "makecell", "xstring", "norm",
84 "barhomogenize", "colordef", "matrix", "type", "isinf",
85 "unique", "getPreferencesValue", "gcd", "isglobal",
86 "whereis", "mode" & "%onprompt".
88 <h2 class="title">Bug fixes</h2>
90 In this version, extra effort has been expended on bug fixing and stabilization.
91 Detailed information about those improvements can be found on the <a href="CHANGES.html">CHANGES</a> file.
93 <h3 class="title">What was new in Scilab 6.0.0</h3>
94 <h2 class="title">New language, new core & new Xcos</h2>
96 This release includes a major rewrite of Scilab's internal
97 core, for better usability and performance: the changes to the
98 visible aspects of the software are limited.
101 The first big internal change is a completely new language
102 parser and interpreter.
105 The language changes are not all backward compatible. You will
106 have to update your scripts/programs/modules, but it will be
107 very simple in pretty much all cases.
110 The second big internal change is the ability to manipulate
111 bigger data sets, without exhausting system resources.
114 Xcos - the graphical tool for dynamic systems modeling and simulation - also uses the
115 new re-written Scilab engine, and is now running in native code, which should provide
116 much better performance as well as support for much bigger models. Xcos can load and
117 run models created with earlier versions of Scilab.
119 <h2 class="title">Utilities for code productivity</h2>
120 <p class="para">This release includes also several features
121 to write better and more efficient Scilab scripts:
123 <li>A full-featured debugger is now included.</li>
124 <li>A new profiler and coverage tool has been added.</li>
125 <li>A "lint"-like command, slint, has been added,
126 for code static analysis: it detects unclear, risky or
127 suspicious code. It is not documented yet, however.</li>
130 <h2 class="title">Newsfeed</h2>
132 A new view is available in the visual environment of Scilab: the
133 "Newsfeed". It provides a continuous feed of news,
134 tips and general communication from the community and from the Scilab Team.
136 <h2 class="title">Licensing changes</h2>
138 Scilab is now released under the terms of the GNU General Public License (GPL) v2.0.
139 Prior to this version, Scilab was licensed under the terms of the CeCILL v2.1 and
140 continues to be available under such terms.
143 In this version, the Intel Math Kernel Library and the FFTW library optimized by Intel
144 Math Kernel Library are included in Scilab. They are subject
