Hi Kunal,

As I understand, you are trying to create a function in MATLAB. Please consult the documentation for the syntax of a function here: http://www.mathworks.com/help/matlab/ref/function.html

In your case the function declaration would look something like this:

function best_attribute = findBestAttribute(x1, x2, x3, x4)

I want to create a function best_attribute = findbestat​tribute(x1​,x2,x3,x4) and I want x1, x2, x3 and x4 to be whole columns. How can I do this?
