Storing vectors into variables in the stack
Vectors can be stored into variables. The screen shots below show the
vectors
u
2
= [1, 2], u
3
= [-3, 2, -2], v
2
= [3,-1], v
3
= [1, -5, 2]
Stored into variables @@@u2@@, @@@u3@@, @@@v2@@, and @@@v3@@, respectively. First, in
ALG mode:
Then, in 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 variables are not purged
previously.
