: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

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

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