Function listing

   time   calls  line
                  1 function y = nonzerosign(x)
                  2 %NONZEROSIGN Signum function excluding zero
                  3 %   For each element of X, NONZEROSIGN(X) returns 1 if the element
                  4 %   is greater than or equal to zero and -1 if it is
                  5 %   less than zero. NONZEROSIGN differs from SIGN in that NONZEROSIGN(0)
                  6 %   returns 1, while SIGN(0) returns 0.
