Drawing N random packet arrivals

Hello everyone, i have a scaled uniform distribution in a given period T=60s. and the total simulation time t=3600s.

 Uniform distribution is the packet of arrivals as this is:
 pd2 = makedist('Uniform','lower',0,'upper',60);

x = -5:0.001:101;
pdf2 = pdf(pd2,x);

figure;

stairs(x,pdf2,'b-','LineWidth',2);

ylim([0 0.1]);
xlim([-5 100]);
that is the distribution of packet arrivals on the interval [0,T]. Here in the flow diagram , the option 'a' the first step is to draw N=200 rand packet arrivals -- fT(t) on T, do you know how to create that step? please help me
