% PDF analysis
pd = makedist('Weibull','a',5,'b',2);
z1 = pdf(pd,CS);
z2 = pdf(pd,SCS);
z3 = pdf(pd,VSCS);
z4 = pdf(pd,ESCS);
figure;
hold on;
plot(CS,z1,'g');
set(gca,'fontsize',16)
ylabel('PDF')
xlabel('Rain rate (mm/h)')
plot(SCS,z2,'k');
plot(VSCS,z3,'b');
plot(ESCS,z4,'r');
legend('CS','SCS','VSCS','ESCS')
% CDF analysis
pd1 = makedist('Weibull','a',5,'b',2);
a2 = cdf(pd1,CS);
a3 = cdf(pd1,SCS);
a4 = cdf(pd1,VSCS);
a5 = cdf(pd1,ESCS);
figure;
hold on;
plot(CS,a2,'g');
set(gca,'fontsize',16)
ylabel('CDF')
xlabel('Rain rate (mm/h)')
plot(SCS,a3,'k');
plot(VSCS,a4,'b');
plot(ESCS,a5,'r');
legend('CS','SCS','VSCS','ESCS')

There may be possiblity in number of cases PDF and CDF are same. If the PDF becomes zero in respective event.
Why donot you consider simple event occurance as a example and check the code?
Cumulative is the total probability of all below PDF
