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:nslope{i}=polyfit(x,y(:,i),1)end`

However, this gives me a 1xn cell with each cell having a 1×2 double with slope AND intercept. I just want a nx1 vector containing the slopes. Any help would be greatly appreciated!
