for i = 1:n
fprintf('%s', repmat(' ', 1, n-i));

Note that this is a homework question

mea culpa
I got carried away.
n = 9;
disp(char(10 * (abs(-n+1:n-1) < (1:n).') + ' '))
Or with a function:
affAbre(n)
function affAbre(n)
s = repmat(' ', 1, 2*n-1);
for k = 0:n-1
s(n-k:n+k) = '*';
disp(s)
end
end
Come on. Be a little bit creative. Try to understand the given solutions and invent a new one.
Of course, I assume that this is a homework question and posting solutions does not help you. I hop, the different approachs motivate you to learn Matlab.
