A Numeric Matrix Processor / Calculator

# :abacus: Matrix Processor

*Recommended for anyone studying Matrices & Determinants during Online Classes :sunglasses:*

This program can accomplish tasks such as addition, subtraction and multiplication of matrices along with finding determinants and inverses of a matrix. *May be* pretty helplful in online classes to calculate on the fly.

It can calculate ~85 % of NCERT questions. Trust me, I myself have used this in my math class and the teacher was really impressed.

**MVP: Finding Inverse**

# Usage

Numeric Matrix Processor
1. Add Matrices
2. Multiply matrix by a constant
3. Multiply matrices
4. Transpose matrix
5. Calculate a determinant
6. Inverse matrix
0. Exit
Your choice: > 3
Enter size of first matrix: > 3 3
Enter first matrix:
> 1 7 7
> 6 6 4
> 4 2 1
Enter size of second matrix: > 3 3
Enter second matrix:
> 3 2 4
> 5 5 9
> 8 0 10
The result is:
94 37 137
80 42 118
30 18 44

Finding inverse of a really complex matrix to show how cool this is.

- Answer is correct. I checked on Wolfram-Alpha :-)
