Pascal's triangle: Difference between revisions

</pre>

Another way to get a formated pascals triangle is to use the convolution method:

<pre>>>

x = [1 1] ;

y = 1;

for k=8:-1:1

fprintf(['%', num2str(k), 'c'], zeros(1,3)),

fprintf('%6d', y), fprintf('\n')

y = conv(y,x);

end

</pre>

The result is:

<pre>>>

1

1 1

1 2 1

1 3 3 1

1 4 6 4 1

1 5 10 10 5 1

1 6 15 20 15 6 1

1 7 21 35 35 21 7 1
