Step 1: Understanding column matrix
A column matrix is a matrix where the number of rows is greater than the number of columns, and it consists of a single column. The general form is: \[ \begin{bmatrix} a_1 \\ a_2 \\ a_3 \\ \vdots \\ a_n \end{bmatrix} \]
Step 2: Conclusion.
Thus, a column matrix is a matrix that has only one column, with multiple rows.
If A and B are two n times n non-singular matrices, then
