Find the transpose of the matrix: $\left[\begin{array}{rr} {1} & {-1} \\ {2} & {3} \end{array}\right]$
✓
Answer
We know that transpose of a matrix is obtained by interchanging the elements of the rows and columns. In other words, we can say, if $\mathrm{A}=\left[\mathrm{a}_{\mathrm{ij}}\right]_{m \times \mathrm{n}} \text { then } \mathrm{A}^{\prime}=\left[\mathrm{a}_{\mathrm{ji}}\right]_{\mathrm{n\times m}}$ So, let $B =$$\left[\begin{array}{cc} {1} & {-1} \\ {2} & {3} \end{array}\right]$ Therefore, transpose of the given matrix B denoted by B’ is given by $ B' $= $\left[\begin{array}{cc} {1} & {2} \\ {-1} & {3} \end{array}\right]$ So,Transpose of the given matrix is $\left[\begin{array}{cc} {1} & {2} \\ {-1} & {3} \end{array}\right]$
