Hello, Could you please give me more information about 'sigma' in Gaussian MF function in matlab? I can't understand it. Thanks

In the function
y=gaussmf(x, [sig c])
'sig' is the standard deviation. The standard deviation describes how much the data as a whole deviates from the mean. Graphically, it affects how tightly the resulting bell curve is fit around the mean: the smaller the standard deviation, the tighter the fit.
