Write MATLAB function t = pasctri(n) that generates the Pascal triangle t up to the level n.

Remark. Two-dimensional arrays in MATLAB must have the same number of columns in each row. In order to avoid error messages you have to add a certain number of zero entries to the right of last nonzero entry in each row of t but one. This t = pasctri(2).

t =

1 0 0

1 1 0

is an example of the array t for n = 2.
