$b = [\begin{array}{c} - 1 & 2 & 5 & 0 \\ - 5 & 9 & 0 & 7 \\ 9 & 12 & 8 & - 1 \\ 8 & - 5 & 0 & 6 \end{array}]$

단계 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 $b$ , the matrix dimensions are written as $b_{m \times n}$ .

단계 2

The number of rows is $4$ .

$m = 4$

단계 3

The number of columns is $4$ .

$n = 4$

단계 4

The given matrix has dimensions $m \times n = 4 \times 4$ .

$b_{m \times n} = b_{4 \times 4}$
