To use this calculator locally on your device,

1. Either download this entire repository or clone using:

git clone https://github.com/BurraAbhishek/Matrices_ElementaryOperations.git

2. Next, open the index.html file in your preferred browser. This program works well across all modern browsers, including Internet Explorer 8+.

Usage

Step - 1

Enter the number of rows and columns of the matrix.

Alternatively, you can import saved operations directly using the upload button. Skip step 2 if you choose this option.

Step - 2

Enter the values in each cell. Blank cells default to 0. A sample setup is as follows:

NOTE: In later releases, all buttons are wide.

Step - 3

Use Select an operation to choose and perform elementary operations on your matrix.

Privacy Policy

1. All operations are performed in the browser. No information is transmitted over the Internet while you're using this app.
2. This application uses browser storage (DOM storage) to store user preferences on light mode and dark mode.
3. When you're saving your progress, it downloads a JavaScript file. This file contains an array which stores the timestamp of saving the file and the saved calculations. You can only upload these JavaScript files to load your calculation history. This file is described in the following section:

The saved calculation history

The calculation history JavaScript file is as follows (The downloaded file is not indented, and everything is in one line):

var matrixoperations_history_file = {
    "timesaved": // Timestamp when the file is saved,
    "history_data": [
        {
            "description": //Description of the operation,
            "matrix": [
                // The saved state of your matrix
            ]
        }
        ...
    ]
};

• This file is an example of the file which will be downloaded when you're saving calculation history.
• This file is a more readable version of the above file.
• This file is the JSON version of the above file: remove var matrixoperations_history_file = at the beginning and ; at the end of the downloaded file, remove trailing commas if any, and save it as a JSON file.
