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

• Cut / copy code source from `processor.py` and paste to run via your favourite editor.
• repl.it button coming soon

# Demo [GIF Coming Soon]

1. Matrix Multiplication
``````Numeric Matrix Processor

2. Multiply matrix by a constant
3. Multiply matrices
4. Transpose matrix
5. Calculate a determinant
6. Inverse matrix
0. Exit
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``````
1. Finding inverse of a really complex matrix to show how cool this is.

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

The code may (most certainly) have bugs. Please feel free to open up an issue describing how I messed up (in a polite way please.)
