CHAPTER 2 — Column and Row Matrix Addition
Here are some of the terms we have been using:
- point — a geometric object; a location in 3D (or 2D) space.
- vector — a geometric object that has properties of direction and length,
but not location.
- column matrix — an ordered list of numbers arranged into a column.
- row matrix — an ordered list of numbers arranged into a row.
- element — one of the numbers that makes up a column or row matrix.
- dimension — the number of elements in a column or row matrix.
- displacement — the difference between two locations, expressed as a vector.
This chapter discusses addition and subtraction of column and row matrices.
(Review question.) What is it called when a row matrix is "flipped" into
a column matrix (or when a column matrix is flipped into a row matrix)?
