what function of this? (weibul)

any one can tell me what function of this?

h=fittype('1-exp(-a*x^b)');

[Y,par]=fit(r',P',h,'StartPoint',[1 1]);

Y

par

Pfit=Y(r);

don't really understand your question, but I guess you want to to know what functions are being used above:

fittype: Fit type for curve and surface fitting

fit: Fit curve or surface to data

What you are doing is trying to get the fittype for your data based on the expression 1-exp(-a*x^b) and then using that fittype which you have in 'h' now to fit a curve to your data using

[Y,par]=fit(r',P',h,'StartPoint',[1 1]);
