Algeo01-20016 - Matrix Calculator

General Information

A matrix calculator made in Java with simple GUI using java.swing library. This repository contains files needed for Tubes 1 Algeo. The project we're making is a Java library for Linear Algebra problems (specifically matrices). This includes SPL, Determinant, Inverse, and others. Contributors:

How to run our matrix calculator?

(if already compiled go to step 3)

1. Go to src folder
2. Compile all source code files with this command: javac -d ..\bin Matrix/*.java Algorithm/*.java Utility/*.java Main/*.java
3. Go to bin folder
4. Run the Main.Main program using the command : java Main.Main

• note: if UnsupportedClassVersionError, recompile the code using step 2. this means your java version doesnt support.
