First Major Assignment IF2123 Geometric and Linear Algebra

Description

This program is developed to to fulfill the First Major Assignment of IF2123 Linear Algebra and Geometry course. Here we use Java programming languages to develop this program. This program is intended to:

1. Calculate solution of System of Linear Equations using Gauss Elimination, Gauss-Jordan Elimination, Inverse Matrix, and Crammer rule.
2. Calculate matrix's determinant using Gauss Elimination and Cofactor Expansion.
3. Calculate inverse matrix.
4. Solve polynomial interpolation problem and multiple linear regression.

This program contain several directories:

1. bin directory contains binary codes or *.class files
2. docs directory contains documentation and report of this assignment.
3. lib directory contains jar file (library of this program).
4. src directory contains java files or source codes of this program.
5. test directory contains test case files for this program.

How to Run

Install dependencies

Here are some things that need to be downloaded and install first:

• Java
• Java Development Kit

Execute program

1. Clone this repository

   git clone https://github.com/hafidznrg/Algeo01-20056.git

2. There are several ways to run this program:
   • Using command line

     cd src
     javac -d ../bin ./*.java
     cd ../bin
     java Main

   • Using run.bat file, you can either use run command in root folder or open the file with double click
   • Using jar file

     cd lib
     java --enable-preview -jar Algeo01-20056.jar

Please note that when read and write file, you only need to specify file name without the directory, for example: input_1a.txt, input4.txt, input_7.txt. Default directory is on test folder. if you want to make new file for test case, kindly make it on test folder. Also don't use Java Process Console if you want to read and write file.
