Winmat for Windows 95/98/ME/2K/XP/Vista (280K) (23 Dec 06)
Click the above link to download the program.
Winmat allows the user to calculate and edit matrices, and solve standard linear algebra problems. The program operates in real, complex, and integer mode.
If the program behaves strangely, there is a page of FAQ, which may help. If not, you can e-mail me at the address found in the program’s Help|About dialog box.
Follow the links for more information about the Windows 95/98/ME/2K/XP/Vista version or the Windows 3.1 version.
Foreign-language version:
Portuguese (prepared with the help of Adelmo Ribeiro de Jesus) (23 Dec 06 )
23 Dec 2006: It was reported that I inadvertently compiled the latest version with the wrong set of background colors. This has been corrected.
20 Nov 2006: Discovered how to word-wrap my help texts. I await news of unintended consequences.
28 Dec 2005: In response to users reporting difficulty opening files by double-clicking file icons, new versions have been prepared that deal with file-naming conventions that allow spaces (and extra periods). See the FAQ.
31 Jan 2005: Minor corrections: The text windows (help files, notebooks, tables, etc) were losing their carets (the blinking thing) now and then, and were not opening files correctly.
15 Jan 2005: It seems that the old “search” function that I installed years ago in text windows no longer works under Windows XP, so I had to revise it.
4 Jan 2005: Fixed the “Copy column” process, which was crashing occasionally.
18 Dec 2004: Fixed a minor glitch — the program was allowing the user to perform matrix calculations while editing was underway.
6 Dec 2004: The One|Calc routine was crashing when matrices were displayed with 0 decimal places. Should be ok now.
4 Dec 2004: A user reported that the echelon-form window was not working for complex matrices. Should be ok now.
28 Aug 2004: Matrices can now be entered via a formula(i,j) [in real mode].
10 Jul 2004: Fixed a bug that was preventing the program from finding characteristic roots for matrices with repeated roots.
19 Jun 2004: Posted the Portuguese version today.
3 Apr 2004: Fixed a few bugs, mostly in integer mode. It was necessary to restructure the program so that all calculations are now controlled by the main menu, including trace, determinant, rank, and characteristic polynomials for individual matrices. This repair was complicated enough that additional bugs may have been introduced, so please let me know if you find any.
1 Feb 2004: In integer mode, the parser was not dealing with numbers of more than three digits. Should be ok now.
27 Dec 2003: At long last, finished the new version of Winmat. I await suggestions and reports of bugs.
