Hi, I want to generate a random integer vector of range 1 to 10. The vector must contain all random integers in range except for 1 and 4. Regards, Muhammad Waqar Ahmed

Do you want to generate just one random number from 1 to 10? Or what is the length of the vector that you want to produce?

V = [2, 3, 5, 6, 7, 8, 9, 10];
randV = V(randperm(length(V)));

V = [2, 3, 5, 6, 7, 8, 9, 10];
randV = V(randi(length(V)));

If you have the statistics toolbox, you can use the following idea:
randsample([2 3 5 6 7 8 9 10], 5, 1)
This produces 5 random numbers from the set, with replacement.
