What is a 3 x 2 matrix?

A 3 x 2 matrix is a rectangular array of numbers with 3 rows and 2 columns. It can be represented as:

[ \begin{pmatrix} a_{11} & a_{12} \ a_{21} & a_{22} \ a_{31} & a_{32} \end{pmatrix} ]

where each ( a_{ij} ) denotes an element in the matrix. This type of matrix is often used in various mathematical applications, including linear transformations and solving systems of equations.
