naming the figure in loop
3 views (last 30 days)
i had written a code for 100 points and to have a leasr square fit i had too first 5 points and jiust slided it till the end now for that i lave lmited the loop till 95 and plotted a least cureve fit now i have to plot the last 5 points in a single plot how should i do that and also i have done a looping of first 5,7,9 points so i amgetting 3 graph now i have to name the 3 figures how can i do that

The Savitzky-Golay filter is a sliding polynomial fit. You can set up a window width of 5 elements and slide it along your vector fitting each set of 5 numbers to a polynomial of order 1, 2, 3, or 4. The sgolayfilt() function in the Signal Processing Toolbox does this for you. You just give it your data, the window width you want, and the order of the polynomial and it returns the filtered output vector.
I'm attaching the 3 sgolayfilt() demos I have. Adapt as needed.
To name figures in a loop you can do this
for k = 1 : 3
hFig(k) = figure;
hFig(k).Name = sprintf('This is my figure #%d', k);
