In the "Section 5 - Further Practice" of MATLAB Onramp, it is stated that, "Indices can be non-consecutive numbers. Try extracting the first, third, and sixth elements of density.". How to do it ?

You would use:

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

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

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

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.
