How to fit a number of curves

Hi,
I have a number of curves that have the same trend and relatively close to one another on the same plot and wish to fit these curves so that they can be represented by a single curve. Please advise me on how to do it.
Thanks
Isa

You could fit the mean (or the median) of the curves. But if you wish to give more importance to larger deviations from the mean, then you would use different techniques.
What kind of curve are you planning to fit?

allX = [x1,x2,x3,x4,x5,x6];
allY = [y1,y2,y3,y4,y5,y6];
A = [log(allX(:)), ones(length(allX),1)];
B = log(allY(:));
C = A \ B;
sortX = sort(allX);
plot(sortX, exp(C(2)) * sortX .^ C(1))
