Question
Write the matrix with the given elements In each case, specify the dimensions of the matrix.$$a_{11}=-1, a_{41}=-5, a_{31}=1, a_{21}=1$$
Step 1
The first index of $a_{ij}$ denotes the row number and the second index denotes the column number. So, $a_{11}$ is the element in the first row and first column, $a_{21}$ is the element in the second row and first column, and so on. Show more…

Matrices: Definitions and Notation
Write the matrix with the given elements In each case, specify the dimensions of the matrix. $$\begin{array}{l} a_{11}=1, a_{31}=2, a_{42}=-1, a_{32}=7, a_{13}=-2 \\ a_{23}=0, a_{33}=4, a_{21}=3, a_{41}=-4, a_{12}=-3 \\ a_{22}=6, a_{43}=5 \end{array}$$
Give the dimensions of each matrix. $$ \left[\begin{array}{rr} {3} & {-7} \\ {4} & {5} \\ {-1} & {0} \end{array}\right] $$
