Undefined function or variable 'detectORBFeatures'

While running the example program from https://www.mathworks.com/help/vision/ref/detectorbfeatures.html

I=imread('ncp.png');
%I = im2gray(I);
points = detectORBFeatures(I);
figure
imshow(I)
hold on
plot(points,'ShowScale',false)
hold off

error coming as,

Undefined function or variable 'detectORBFeatures'.

Error in orb_test (line 8)

points = detectORBFeatures(I);
