HP-50g Algebraic matrix expressions

[Wes Loewer]

FWIW, the GET command can also be used in Algebraic mode.

GET(matrix,{r,c})

It's not as nice looking as matrix(r,c), but GET can be used with a literal matrix.

[[10,20][30,40]]->MM
GET(MM,{2,2}) AND MM(2,2) both return 40.
GET( [[10,20][30,40]],{2,2}) works but [[10,20][30,40]](2,2) does not.
Likewise, GET(Ans(1),{2,2}) works but Ans(1)(2,2) does not.
