Accessing Vector/Matrix components? Graphing vectors?

[baykus]

Hi

I have couple questions about vectors in Nspire. I am hoping that
someone might have answers to my issues with vector variables.

- How do I access components of a vector? For example how do I get the
value of first component of a vector and use as a variable? Lets say I
have a vector that is v=[3,4,5] and I want to use the 3rd part which
is 5 as a variable. Obviously I can write the numeric value manually
but that is useless in a short script or calculator or a graph page.

- I want to be able to graph bunch of vectors on a graph page. Lets
say I have v1,v2,v3..vn vectors and I want to be able to graph these
on the same page?

- Can I pass vector variables to functions/parametrics etc for
graphing?

thanks

If you say v:=[3,4,5] then v[1,1]=3, v[1,2]=4 and v[1,3]=5
May or may not be the simplest way to do this.
