Software
by Zvika Ben-Haim
These are programs I wrote for fun or as small exercises. Please feel free to download and use them. You can also download the source code for all of these programs and modify it any way you like (but please give credit where due). If you do anything neat with any of these, let me know!
Note: Some of these programs were previously released as shareware, and, in some cases, the documentation still indicates shareware status. However, I am no longer trying to sell these as shareware. Instead, the versions you see here are the complete ("registered") versions. On the other hand, I don't always have time to answer technical support questions related to these programs.

IguanaTex: An add-in for PowerPoint that allows you to easily insert LaTeX equations into your presentations. |
|
|
Siper: An educational tool for image and video processing developed (with Alex Grechin and Oded Green) as part of my work in SIPL. |

Blind Minimax Estimation: This website includes a friendly introduction to blind minimax estimation, some examples, and a BME package for Matlab which you can download and use. |

Converting latitude and longitude to the Israel grid. This is a small Java applet and smartphone Java midlet for translating Earth coordinates (longitude and latitude) to Israel grid coordinates. Both the new ITM grid (רשת ישראל החדשה) and the old ICS grid (רשת ישראל הישנה) are supported. |

MUSE: Musical Database Search by Audio Query. This is a computer program for automatic song identification. The user hums a few notes from a song; these are analyzed and searched for in a database. This was the graduation project of my bachelor's degree at the Technion, and was conducted under the supervision of Gal Ashour. |
 |
Kakuro Solver: A program for automatically solving Kakuro (also known as Cross Sum) puzzles. No documentation, but you'll figure it out if you know the puzzle. Solves most large puzzles (22x13) in a few seconds. Requires .NET Framework 2.0. Download executable (with example) or source (Visual C# 2005 Express) |
 |
Sudoku Solver: A program for automatically solving Sudoku (a.k.a. Number Place) puzzles. Just fill in the numbers you know and leave the others blank, and the program will solve the puzzle for you in under a second. Download the software, sample puzzles, and source (MFC/Visual C++ 6). |
 |
WakeUp: Alarm clock program. Choose to play a wave file or run an external program (e.g. Media Player) at a specified time. The cool feature is the ability to slowly increase the computer's volume, so you don't wake up with a start. Download the executable (with help file) or the source (MFC/Visual C++ 6). |
 |
Guitar Tuner: A program to tune your guitar. Connect a microphone and strum a single note on your guitar, and the program will tell you if you're sharp or flat. (Written as a birthday present for my brother Rafi, who was learning to play.) Download executable or source (MFC/Visual C++ 6). No documentation, but quite straightforward to use. |
 |
Shchor: This program solves the Paint by Numbers (Pic-a-Pix) puzzle, in which the horizontal and vertical lengths of pixel sequences are given, and the object is to figure out the picture. No documentation, but if you know the puzzle, you'll figure it out; just drag one of the enclosed text files into the program and click Action>Solve. (boat.txt is a good starting example; carriage.txt is a difficult one.) Download the software (with sample puzzles) or source (MFC/Visual C++ 6). |
 |
21 Questions: In this guessing game, the computer asks a series of yes/no questions to figure out what concept you are thinking of. The program learns new concepts if its guesses fail. Concepts of different types can be programmed; for example, a sample question database which can identify over 100 types of animals is included. If you create different databases or substantially enlarge this one, let me know! Download software (with help and animals database) or source (C++). |
 |
DrMatrix: C++ package for basic matrix/vector operations, such as matrix ranking, inversion, determinants, etc. However, this package probably does not house the most numerically stable algorithms, as it was written primarily as an exercise. Download the package source code (C++), with documentation and demo program for solving linear equations. |
 |
MidiMix: A program for converting MIDI files to the XM (Extended Module) music format. Before MP3s became popular, XM was used for storing sound files in a higher quality than MIDI. Download software (with documentation and examples) or source (ANSI C++) |
