MATLAB: Can someone help me with the code? It giving me an error in line 2 saying that it doesn’t exist or it inst able to enter it in as x.

function y = bubble( x )
n = length(x);   %This is where the error occurs
sort= 0;
k = 0;
while ~ sort
    sort =1;
    k = k+1;
    for j = 1:n-k
        if x(j)>x(j+1)
            temp = x(j);
            x(j)=x(j+1);
            x(j+1) = temp;
            sorted = 0;
        end
    end
end
p=x

Best Answer

Show us how you're calling the function and what you're passing in for x. Like in your main program do this
% define x
x = ...... whatever you do
whos x    % Let's see what it is
y = bubble( x )
Then come back here and paste the results of the "whos" command that will show up in the command window.
