Hi, i am currently trying to use a bubble sort for a series of inputed numbers but im getting an error on line 2.

can someone please explain why i am getting this error and how to fix it.

thank you in advance.

here is my code and the error: Error in Bubble1 (line 2)

cases = input('Enter cases with [ ] around them:');

cases = input('Enter cases with [ ] around them:');
sorted_array = bubble_sort(cases)
function array = bubble_sort( array )
for i = 1:length(array)
  
    for j = 1:length(array)-i
    
        if(array(j)>array(j+1))
            temp = array(j+1);
            array(j+1) = array(j);

You code can run. if you use "input", key in the following "[1 3 2 5 2]" without quotes.

%cases = input('Enter cases with [ ] around them:');
cases = [1 3 2 5 2]
cases = 1×5
     1     3     2     5     2
sorted_array = bubble_sort(cases)
sorted_array = 1×5
     1     2     2     3     5
function array = bubble_sort( array )
for i = 1:length(array)
  
    for j = 1:length(array)-i
    
        if(array(j)>array(j+1))
            temp = array(j+1);
            array(j+1) = array(j);
            array(j) = temp;
        end
    end
end
end
