Vedclass · Answer

(A) The matrix $A$ is of order $3 	imes 4$,where $i \in \{1, 2, 3\}$ and $j \in \{1, 2, 3, 4\}$.The elements are calculated using $a_{i j} = 2i - j$:For $i=1$: $a_{11} = 2(1)-1 = 1, a_{12} = 2(1)-2 = 0, a_{13} = 2(1)-3 = -1, a_{14} = 2(1)-4 = -2$.For $i=2$: $a_{21} = 2(2)-1 = 3, a_{22} = 2(2)-2 = 2, a_{23} = 2(2)-3 = 1, a_{24} = 2(2)-4 = 0$.For $i=3$: $a_{31} = 2(3)-1 = 5, a_{32} = 2(3)-2 = 4, a_{33} = 2(3)-3 = 3, a_{34} = 2(3)-4 = 2$.Thus,the required matrix is $A = \begin{bmatrix} 1 & 0 & -1 & -2 \ 3 & 2 & 1 & 0 \ 5 & 4 & 3 & 2 \end{bmatrix}$.

Construct a $3 \times 4$ matrix,whose elements are given by $a_{i j}=2 i-j$.
