CHAPTER 01.03: INTRODUCTION: What is a column vector? Let’s define what a column vector is in this
segment. A matrix is called a column vector if it has one column. So let’s
look at what a typical column matrix would look like. So it would have
elements such as C 1, C2 all the way up to CN. So what that means is that is
has N elements in it; so the dimension of this column vector is N. The
dimension of the column vector is N. Let’s look at an example. Somebody says “Hey my C
matrix is 50, -20.5, 30, -60,” let’s suppose. So in this case it is a column
vector because it only has one column in it but it has 4 elements. 1, 2, 3,
4. So the dimension for the column vector is 4. And that’s the end of this
segment. |
