Curve Fitting on Histogram
显示 更早的评论
Hi, so I am trying to fit a polynomial curve on the histogram data, but I have problem in the implementation. I am using the function 'histfit' like so:
[j,qout] = hist(data,700);
h = histfit(data, 700, 'beta');
but it's coming with an error, stating:
All values must be within the closed interval [0,1].
I don't see such an implementation on the documentation of the function. Help would be much appreciated.

Hi Ahmed,
if I use
data = rand(1e6,1);
it works flawlessly, but if I use
data = 2*rand(1e6,1);
I get the same error. As the error suggests, the function only works on Data Ranges [0,1].

data = data./max(data)
should normalize your data. Maybe check first if max(data)>0 :)
