Test Exam II : Question 62

Question 62 : Which of the following statements is true:
I. A row vector can have only one column

Answer 62 :
A row matrix is of the order 1 x n, where n is the number of columns. It has only one row and many columns. Statement I is not true, it would be true of a ‘column vector’ though.

A scalar can be viewed as a 1×1 matrix, which is also a row vector with 1 colum. I’d say the statement could be considered as ‘true’.

Agreed. And thank you for pointing this out. But I would probably think that the 1 x 1 case is more of a unique case than the general rule. I have modified the explanation for the answer to include this observation – but without changing the answer.
