Solving system of linear equations.
Loads matrix and vector for the system of linear equation to solve from input.txt file located in working directory.
-
Using CMake
$ cmake . $ make $ ./cequsys -
Using GCC (since it's just one file)
$ g++ cequsys.cpp -o cequsys $ ./cequsys
Generate equation system with following pattern with command ./gen.py {size} > input.txt.
2 2 0 0 0 0 ; 2
2 2 2 0 0 0 ; 2
0 2 2 2 0 0 ; 2
0 0 2 2 2 0 ; 2
0 0 0 2 2 2 ; 2
0 0 0 0 2 2 ; 2
Note that it's possible to use fractions using / and without spaces between.
1/3 1/3 0 0 0 0 ; 1/3
1/3 1/3 1/3 0 0 0 ; 1/3
0 1/3 1/3 1/3 0 0 ; 1/3
0 0 1/3 1/3 1/3 0 ; 1/3
0 0 0 1/3 1/3 1/3 ; 1/3
0 0 0 0 1/3 1/3 ; 1/3
Running example from input.txt user should get following results:
1.91616;1.60141;1.44354;1.40138;1.46393;1.64751
Code should be formatted with ./format.sh script (which internally uses clang-format).
It's a revitalized project from college at Cracow University of Technology.
