RGB: A Linear Algebra Library for Java

RGB is a Java-based application that performs essential linear algebra operations. Initially developed as a command-line tool for the Linear Algebra and Geometry course at Institut Teknologi Bandung, it now includes a graphical user interface (GUI) for enhanced user experience. RGB supports operations like solving linear systems, performing regression and interpolation, matrix transformations, and more.

⚠️ Note: While most features are fully functional, some advanced features may still require further optimization and testing.

📦 Installation & Usage

Requirements

• Java 21 or later
• Gradle 8.8 or later (if building from source)

Running the Application

You can now run the application in two modes: via Command-Line Interface (CLI) or Graphical User Interface (GUI).

1. Command-Line Interface (CLI) Mode

1. Download the JAR file from the releases page.
2. Open a terminal and navigate to the directory containing the downloaded JAR.
3. Run the following command to start the application in CLI mode:

   java -jar Algeo01-23002.jar -cli

Alternatively, if you have cloned the repository and want to run it using Gradle:

./gradlew run --args="-cli"

2. Graphical User Interface (GUI) Mode

1. Follow the same steps as above to download the JAR file.
2. To run the application in GUI mode, use the following command:

   java -jar Algeo01-23002.jar

Or, if using Gradle:

./gradlew run

✨ Features

1. Linear System Solver

• Solve systems of linear equations using Gaussian elimination, Gauss-Jordan elimination, Cramer's rule, and matrix inversion methods.

2. Matrix Operations

• Perform operations such as matrix multiplication, transposition, finding the determinant, and calculating the inverse of matrices.

3. Regression Analysis

• Supports both Multiple Linear Regression and Quadratic Regression for data analysis.

4. Interpolation

• Polynomial interpolation and Bicubic Spline Interpolation for estimating values between data points.

5. Graphical User Interface (GUI)

• An intuitive GUI for easier interaction with the library, allowing users to perform operations without needing to use the command line.

6. Command-Line Interface (CLI)

• A fully-featured CLI for power users who prefer or need to interact with the application through terminal commands.

7. Image Resizing and Stretching

• Resize images using Bicubic Spline Interpolation, improving image quality and scaling.

8. Extensive Error Handling

• Handles invalid inputs and matrix dimension mismatches gracefully with detailed error messages.

📝 Notes & Limitations

• This release (v1.0) includes the first iteration of the GUI, which is fully functional for most features.
• Matrix operations involving larger matrices may still be slower than desired.
• Bicubic Spline Interpolation and image resizing functionality have been added.
