What makes you think anything is wrong with it? What error messages are you getting? Wrong answers?
Without knowing the values of ev & evu, there is not much we can do to help.
One possibility: it is bad practice to compare real numbers for equality as in:
if evu(r,i)==ev(i)
You should consider something like:
if abs(evu(r,i)  ev(i)) < tol
instead. Where tol is a "small" number.
