hp prime - command syntax
Message #1 Posted by bluesun08 on 9 Nov 2013, 10:39 a.m.

i'm interested in the "slope" command. After pressing the help-key the calculator show the following syntax:
slope(Line| |Pnt| |Cplx,[Pnt| |Cplx])
How can i read the symbols | [ ? What means that? How can i use the command? The example in the Help-menu is not very instructive for me.

The square brackets [] just mean that entry is optional. The Where symbol | is available in the Catlg list in the Toolbox.

"||" in a syntax is not the Where function (nor absolute value); it means "OR". Example:

row(Mtrx(A),Intg(n)||Interval(n1..n2))

means there are two options:

(1) row(Matrix, Integer)
(2) row(Matrix, Interval)

o.k. thank you. it works also for me in cas. But for heaven's sake (or what the hell) do i know if i can use an app function only in home-view or only in cas-view or in both views?
