even E Kim arks New folder Matlab programming exercises ME345 Modeling and Simulation Problem 1. Write a Matlab code that will allow a user to enter in a \"critical number\" between 0 and and then track the number of times that a random number must be generated in order to be greater than the \"critical number\". Output the number of attempts that were necessary, and the numbers that were not successful. Be sure that you code is working correctly. (Hint: the command rand will be useful here)

Solution

%%% Program 1

clc;
clear all;
critical_num=input(\'Please Enter A Critical Number between 0 and 1 \ \');
i=1;
greater=0;
stop=0;
while(stop==0)
rand_num(i)=rand;
disp(rand_num(i));
if(rand_num(i)>critical_num)
greater=greater+1;
end
stop=input(\'Do you want to generate another random number(1=STOP, 0=CONTINUE)\ \');
i=i+1;
end
fprintf(\'Total Generated Random Numbers are : %d \ \',(i-1));
fprintf(\'Successful Generation of greater than critical number is : %d \ \',greater);
fprintf(\'Unsuccessful Generation of greater than critical number is : %d \ \',(i-1-greater));
