Find the order of following matrix `X=({:(1,0,2,1),(2,1,0,3),(0,0,1,2),(1,0,3,2):})`

Explanation

To find the order of the given matrix \( X = \begin{pmatrix} 1 & 0 & 2 & 1 \\ 2 & 1 & 0 & 3 \\ 0 & 0 & 1 & 2 \\ 1 & 0 & 3 & 2 \end{pmatrix} \), we will follow these steps:

### Step 1: Identify the number of rows
We need to count how many horizontal lines of numbers (rows) are present in the matrix.

- In matrix \( X \), we can see that there are 4 rows:
1. \( (1, 0, 2, 1) \)
2. \( (2, 1, 0, 3) \)
