hi, i have function from my supervisor. this is non weibul and weibul function.

N=100; % The number

% n(k) the number

%n=[4 5 3 4 8 4 5 6 ];

P=ones(size(n));% Kumulative Probability

p=ones(size(n));% probability with number k;

L=length(n);

r=(1:L)

for m=1:L;

p(m)=n(m)/N;

end; % p(1)=0.1; P(1)=p(1);

for m=2:L;

P(m)=P(m-1)+p(m);

end;

Pfitconst=constProb(p)

figure(1)

plot(r,Pfitconst,r,P,'*'); ----------------------

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

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

par

Pfit=Y(r);

figure(2)

plot(r,Pfit,r,P,'o');

. . . . .

i dont know what weibul is. how to explain this in an introduction in a paper.

wiki explain to far from my equation:

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

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

par

Pfit=Y(r);

......

is this weibul?

What is the CDF of a Weibull? These types of questions are best answered by your supervisor or colleagues. Noting about this question is related to MATLAB.
