Dear all,
I got some test data sets and ploted them in excel, the following image is the result.
Left : no smoothing, just connecting each data with direct lines.
Right : connecting each data with default Excel smoothing method.
Excel smoothing method works well.
But I tried some Matlab methods such as interp1, it seemed that they cannot work normally in my data sets.
In my opinion, the reason is that both x value and y value are not monotonous.
So are there any methods provided by Matlab library that can solve this problem?
Or any advice about what method Excel is using to plot a smoothing curve.
Best regards,
Sam

I tried the answer to this question
with your data
x = [-1 -.6 0 .6 1 .6 0 -.6];
y = [-0 .6 1 .6 0 -.6 -1 -.6];
I think it works...
