Storing vectors into variables in the stack

Vectors can be stored into variables. The screen shots below show the vectors

u2 =	, u3 =	, v2 =		, v3 =
Stored into variables		, and		respectively. First, in ALG

	RPN mode (before pressing	K	, repeatedly):

Note: The apostrophes (‘) are not needed ordinarily in entering the names u2, v2, etc. in RPN mode. In this case, they are used to overwrite the existing

variables created earlier in ALG mode. Thus, the apostrophes must be used if
the existing[1,variables2]	are[-3,not purged2,-2]previously.[3,-1]	[1,-5,2]
Vectors can also be entered by using the matrix writer		(third key in

the fourth row of keys from the top of the keyboard). This command generates a species of spreadsheet corresponding to rows and columns of a matrix (Details on using the matrix writer to enter matrices will be presented in a subsequent chapter). For a vector we are interested in filling only elements in the top row. By default, the cell in the top row and first column is selected.

At the bottom of the spreadsheet you will find the following soft menu keys:
