Question

In a lottery the player has to select several numbers out of a list. Write a user-defined function that generates a list of n integer numbers that are uniformly distributed between the numbers a and b. All the selected numbers on the list must be different. Use the function to generate a list of 6 numbers from 1 through 49.

%%Use the MATLAB rand function. To make sure that all the numbers are different from each other, the numbers are picked one by one. Each number that is picked (by the rand function) is compared with all the numbers that were picked before. If a match is found, the number is not selected, and a new number is picked.%%

Example: lotto(1,49,6) ans =
23 2 40 22 31 39
Need to use matlab to solve this question

Explanation / Answer

Dear,

function [ lottory ] = lotto( a, b, size )

lottory = (size);
i = 1;

while i <= size   
    found = false;
     randomNumber = randi(b);
     j = 1;
    while j < i
        if randomNumber == lottory(j)
            found = true;
            break;
        end
        j = j+1;
    end
        if found == false
            lottory(i) = randomNumber;           
            i = i+1;
        end
           
end
end
