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.
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);
array(j) = temp;
end
end
end
end

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
