HP 50g manual Storing vectors into variables in the stack

Storing vectors into variables in the stack

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

u2 = [1, 2], u3 = [-3, 2, -2], v2 = [3,-1], v3 = [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.
