What does [2,1] mean?
What does [2,1] mean?
(OP)
Hello,
using a function with a vector I get a result showing a column with "[2,1]", propably with the size of the vector.
I didn't find anything about that within the help or documentation.
Could anyone explain that?
Thanks

eg
func(b):b+1
called using a matrix c which is a 2 by 1 matricx of 1 s
would give
func(c)=(2,2)

let's say you get d=([2,1]), then "d[0=" should allow you to see the content of the nested array.
If you pick a blank spot to move the edit cursor to and select Format|Result|Display Options and check the "Expand nested arrays] checkbox, you should also see the nested array

RE: What does [2,1] mean?
The "d[0=" and "d[1=" hint shows me the result I was looking for. The second hint didn't work.
Unfortunately I didn't understand your explanation.
I used a formula to add two vectors, so the result is a vector again - so far it's easy, but
I defined the formula as a function with an angle as a parameter.
Then I definded an index i=0...360 and passed the vector of the 360 angles (in radian) as a parameter to the function and the result was as described:
L(angle[i)=[2,1]....
I can't see anything being "nested"?!?

it'll make it much easier to see what's going on.
