What does this do?

[1 3 6]

Answer 1

[Lan Lou]

You would use:

p=density([1 3 6],:)

or

p=density([1 3 6],end)

or

p=density([1 3 6],1)

[Jon Wagner]

p=density([1 3 6],1) is correct. this gives the 1st 3rd and 6th element of column 1. since elements start at the top of the first column and move down, then to top of next column.

[vashisht kant]

all three are correct since there is only one column
