Given an integer n >= 0, generate the length n+1 row vector representing the n-th row of Pascal's Triangle.
Examples:
pascalTri(0)
ans =
1 pascalTri(1)
ans =
1 1 pascalTri(2)
ans =
1 2 1

the last assertion is wrong

Oops, I guess I commented in the solution, not the problem. (What's the difference????) They should check if their answer is symmetrical, which it isn't, so their solution must be wrong regardless of subsequent values

I've removed the last assertion and rescored. Thanks for the note.

"y = arrayfun(@nchoosek, repmat(n, 1, n + 1), 0:n)" gives a score of 23

Why won't syms work? I can run this in MATLAB and it outputs the correct pascal line given n.

We used a subfunction Cpn(n,p)
Y=factorial(p)/(factorial(n)*factorial(p-n)) instead of the function "nchoosek" .

When I submitted the solution "y=round((2^n)*binopdf(0:n,n,0.5));" cody test aborted by saying "binopdf" is an undefined function. Strange !!

binopdf is part of the statistics toolbox, not core Matlab.

How about an assertion on whether or not the sides are symmetric?
This problem's last assertion is wrong :/
isequal(correct(1:27),correct(54:-1:28))
At first I thought it was an issue with accuracy on my end ...
