Project Matrix Calculator

A C/Assembly hybrid matrix calculator program supporting basic operations like Addition, Subtraction, Multiplication, Determinant, and Transpose.

Prerequisites

Before running the program, ensure you have the following installed:

• GNU Compiler Collection (GCC)

  gcc -v

• Make (GNU Make)

  make -v

  (Note: On Linux, make is usually pre-installed. On Windows, you can use MinGW or MSYS2)

Building and Running

The project comes with a Makefile that supports both Linux and Windows automatically.

• To compile the program:

  make

• To run the program:

  make run

• To clean up compiled files:

  make clean

• To run tests:

  make test

📖 Tutorial: How to Use the Program

When you run the program (make run), you will be presented with interactive menus. You can navigate these menus using your Arrow Keys (Up/Down) and press Enter to make a selection.

1. Choosing the Input Method

You can choose to input your matrices via the console manually or read them from a file.

Option A: Console Input

If you select console, the program will ask you step-by-step:

1. How many matrices you want to input.
2. For each matrix, its dimensions (rows and columns).
3. The elements of the matrix row by row.

Option B: File Input (Recommended for large matrices)

If you select file, the program will automatically read from a file named input.txt located in the root directory of the project.

How to format input.txt: The format must strictly follow:

1. The total number of matrices (e.g., 2).
2. For each matrix:
   • The number of rows and columns separated by a space (e.g., 2 2).
   • The values of the matrix (can be separated by spaces or newlines).

Example input.txt (Two 2x2 matrices):

2
2 2
1.0 2.0
3.0 4.0
2 2
5.0 6.0
7.0 8.0

2. Choosing the Operation

After providing the matrices, you will be prompted to select an operation to perform:

• Addition (Requires 2 matrices of the same dimensions)
• Subtraction (Requires 2 matrices of the same dimensions)
• Multiplication (Requires matrices with compatible dimensions)
• Determinant (Requires a square matrix)
• Transpose (Requires 1 matrix)
• Inverse (Coming soon...)
• Exit

3. Choosing the Output Method

Finally, choose how you want to see the result:

• Console: Prints the resulting matrix or determinant value directly to your screen.
• File: Saves the result to a file named output.txt in the root directory.

Note: If output.txt already exists, it will be overwritten.
