To square a matrix, it must be a square matrix, meaning it needs to have the same number of rows and columns. A 2×3 matrix has 2 rows and 3 columns, making it a non-square matrix. Therefore, it is impossible to square a 2×3 matrix.
However, if you want to perform operations on a 2×3 matrix, you can consider its transpose or other transformations, but squaring it in the traditional sense of multiplying it by itself is not feasible.
