MATLAB: Find slope across columns of cell

cellslope

I have a 220×4 cell (a) consisting of numerical data and would like to find the (linear) slope across the four values in row one, then the four values in row two, and so on, so that I would end up with 220 different slopes that I could then save. Thanks in advance!

How are you organizing the data into ordered pairs? I'm assuming that by 'numerical data' you mean you have cells that contain individual doubles.
data = cell2mat(a);
for i = 1:size(a,1)
    slope(i) = polyfit(x_vals,data(i,:),1);
end
