We can now use function EXPAND (in the ALG menu) to expand this
expression:
Thus, the equation of the plane through point P
0
(2,3,-1) and having normal
vector N = 4i+6j+2k, is 4x + 6y + 2z – 24 = 0. In RPN mode, use:
[2,3,-1] ` ['x','y','z'] ` - [4,6,2] DOT EXPAND
Row vectors, column vectors, and lists
The vectors presented in this chapter are all row vectors. In some instances, it
is necessary to create a column vector (e.g., to use the pre-defined statistical
functions in the calculator). The simplest way to enter a column vector is by
enclosing each vector element within brackets, all contained within an
external set of brackets. For example, enter:
[[1.2],[2.5],[3.2],[4.5],[6.2]] `
This is represented as the following column vector:
In this section we will showing you ways to transform: a column vector into a
row vector, a row vector into a column vector, a list into a vector, and a
vector (or matrix) into a list.
We first demonstrate these transformations using the RPN mode. In this mode,
we will use functions OBJ, LIST, ARRY and DROP to perform the
transformation. To facilitate accessing these functions we will set system flag
117 to SOFT menus (see Chapter 1). With this flag set, functions OBJ,
ARRY, and LIST will be accessible by using „° @)TYPE!. Functions
