Question

Which general form represents a column matrix?

Options

• \[B=[b_{ij}]_{1 \times n}\]

• \[A=[a_{ij}]_{n \times n}\]

• \[b_{ij}=0\] when \[i \ne j\]

• \[A=[a_{ij}]_{m \times 1}\]

Answer 1

The general form of a column matrix is \[A=[a_{ij}]_{m \times 1}\]. Here, \[m\] denotes the number of rows and there is exactly one column.
