👉 In mathematics, a "patrix" is a special kind of matrix that has been represented using a row vector. This means that each element in the matrix can be thought of as a column vector, rather than as a single number. Pmatrixes are often used to represent vectors or matrices with more than two dimensions.
For example, consider the following pmatrix:
```
A = [1 2; 3 4]
```
This matrix represents a 2x2 square matrix
