Retrieve just the slope in polyfit

I would like to return a vector containing just the slopes of various regressions so I can compare them. Right now I have a loop:
for i=1:n
slope{i}=polyfit(x,y(:,i),1)
end
However, this gives me a 1xn cell with each cell having a 1x2 double with slope AND intercept. I just want a nx1 vector containing the slopes. Any help would be greatly appreciated!

Sorry, Daniel.x16, but this produces this error in Matlab 2009a and 2011b:
Error: ()-indexing must appear last in an index expression.
