A = ⎡ ⎢ ⎣ \begin{matrix} 3 & 0 - 1 & 2 1 & 1 \end{matrix} ⎤ ⎥ ⎦

$A = [\begin{array}{c} 3 & 0 \\ - 1 & 2 \\ 1 & 1 \end{array}]$

Schritt 1

A matrix is a rectangular arrangement or array of elements. The dimensions of a matrix,

$m \times n$ , identify how many rows and columns a matrix has.

$m$ represents the number of rows and

$n$ represents the number of columns. Assuming that the matrix name is

$A$ , the matrix dimensions are written as

$A_{m \times n}$ .

Schritt 2

The number of rows is

$3$ .

$m = 3$

Schritt 3

The number of columns is

$2$ .

$n = 2$

Schritt 4

The given matrix has dimensions

$m \times n = 3 \times 2$ .

$A_{m \times n} = A_{3 \times 2}$
