MRHS-modifier is tool used for the manipulation with system of Multiple-Right-Hand-Sides (MRHS) equations. It allows manual or heuristic optimalization of the given system. Program can be easily modified and used in various experiments. Thanks to input redirection we can automatize chain of execution of given commands. Implementation of new functionality can be easily (hopefully) done thanks to OOP approach.
Master branch always contains latest source code of the program. These steps will get you a copy of the MRHS-modifier on your local machine.
Java installed on your computer is required. Nothing else.
You can download all source code contained in src folder of master branch. Then you can import source code into IDE of your preferation and build a jar file. If you own NetBeans IDE simply clone this repository and open it as a project. Or you can simply download latest release.
To run the MRHS-modifier simply execute following command in a command line:
java -jar MRHS-modifier.jar
Program supports one additional option:
-f fileName
This will start the program with system of equations given by file fileName. This option is only good for experiments ran by automated scripts.
MRHS-modifier supports these commands:
| Command | Description |
|---|---|
| load | Load a system from file |
| save | Save a system to file |
| random | Generate random MRHS system |
| solve | Execute solver's executable file to solve system |

| deleterow | Delete row |
| swapcol | Swap columns |
| addcol | XOR column with column |
| deletecol | Delete column |
| swapblocks | Swap equations |
| deleteblock | Delete equation |
| glue | Apply gluing algorithm on two equations |
| permuteblocks | Apply permutation on equation order |
