Matrix operations, or matrix math, is a fundamental concept in linear algebra. It involves performing various mathematical operations on matrices. In this tutorial, we will explore the basics of matrix operations, including addition, subtraction, multiplication, and more.

Matrix Addition

Matrix addition is straightforward. You add corresponding elements from two matrices of the same size. Here's a simple example:

  • Matrix A:
    1 2
    3 4
    
  • Matrix B:
    5 6
    7 8
    

To add them, you simply add the corresponding elements:

A + B = 
1+5 2+6
3+7 4+8
6 8
10 12

Matrix Subtraction

Matrix subtraction is similar to addition. You subtract corresponding elements from two matrices of the same size.

  • Matrix A:
    1 2
    3 4
    
  • Matrix B:
    5 6
    7 8
    

To subtract them, you simply subtract the corresponding elements:

A - B = 
1-5 2-6
3-7 4-8
-4 -4
-4 -4

Matrix Multiplication

Matrix multiplication is a bit more complex. You multiply rows of the first matrix by columns of the second matrix. The resulting matrix will have the same number of rows as the first matrix and the same number of columns as the second matrix.

  • Matrix A:
    1 2
    3 4
    
  • Matrix B:
    5 6
    7 8
    

To multiply them, you follow these steps:

A * B = 
(1*5 + 2*7) (1*6 + 2*8)
(3*5 + 4*7) (3*6 + 4*8)
29 34
43 50
