Create a function myPrimes that returns the first n primes as a vector, given a positive integer. For example, if the positive integer is 5, the vector returned would include 1, 2, 3, 5, 7. In your script, prompt the user for the positive integer val

clc; close all; clear all;
n=input('Prime Numbers until:');
function result = myPrimes(n)
    result = [];
    index = 1;
    i = 0;
    num = 1;
    flag = 0;
    i = 0;
    while i < n
        j = 2;
        flag = 0;
        if(num==1)
            flag=0;
        else
            while(j<num)
                if(mod(num,j) == 0)
                    flag = 1;
                end
                j = j + 1;
            end
        end
        if(flag == 0)
            result(index) =  num;
            i = i + 1;
            index = index + 1;
        end
        num = num + 1;
    end
end

This is my current code. In order for it to output the primes I have to type myPrimes(n) with the desired input for n instead of just entering a number and getting an output.

在 MATLAB Online 中打开

Refactor the first two lines to

clc;
n=input('Prime Numbers until:');
output = myPrimes(n)

Edit : Addressed @Rik 's feedback

You should not encourage cargo cult programming. Only clc is needed here.
