Issue regarding output after running a script

I wrote a function that uses the Newton-Raphson method to calculate the value of y for the following equations: x^2 + y^2 - 1 , x*y - 0.5 .

The output gives me the Results followed by ans = 11 (which im assuming is the number of iterations it took to converge.) How do I get rid of the "ans = " part?

The last y value converges to:  0.7071

ans =

      11

function [result1,result2] = NR3()

syms x y
f1 = input('\nPlease Enter equation 1: ');
f2 = input('\nPlease Enter equation 2: ');
y0 = input('\nPlease Enter an initial y value: ');
tol = input('\nPlease Enter a tolerance: ');

f_x = solve(f2,x);
f_y = subs(f1,x,f_x);

dfdy = diff(f_y,y);

d_w = [];
yy_w = [];
yy_w(1) = y0;
tol1 = 100;
i = 1;
while tol1 > tol
    i = i + 1;
    d_w(i-1) = subs(f_y,y,yy_w(i-1))/subs(dfdy,y,yy_w(i-1));
    yy_w(i) = yy_w(i-1) - d_w(i-1);
    tol1 = abs(yy_w(i) - yy_w(i-1));
end

format long

if isnan(yy_w(end))
    result1 = fprintf('\nError: Divergence! ');
    result2 = fprintf('\nPlease try a different initial value. \n');
else 
    result1 = fprintf('\n\nResults\n\n');
    result2 = fprintf('The y value converges to: %7.4f\n',yy_w(end));
end   

end

That isn't a script, it is a function.

To get rid of the "ans=", invoke your function as

NR3;

with the semi-colon.

Please also re-read the documentation for fprintf(), and in particular pay attention to what the output from it is.
