[\begin{matrix} 1 & 0 0 & 2 \end{matrix}]

$[\begin{array}{c} 1 & 0 \\ 0 & 2 \end{array}]$

Schritt 1

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

m \times n

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

m

$m$ represents the number of rows and

n

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

A

$A$ , the matrix dimensions are written as

A_{m \times n}

$A_{m \times n}$ .

Schritt 2

The number of rows is

2

$2$ .

m = 2

$m = 2$

Schritt 3

The number of columns is

2

$2$ .

n = 2

$n = 2$

Schritt 4

The given matrix has dimensions

m \times n = 2 \times 2

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

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

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