%read image
I = imread('C:\Users\LENOVO\Desktop\Genuine\2\2.2.png');
I2=rgb2gray(I);
%Detect SURF features.
points = detectSURFFeatures(I2);
%Display locations of interest in image.
imshow(I2); hold on ;
plot(points.selectStrongest(10
));

The following error is occured:

Error in (Line 7)

You have named your script feature.m. Though it's not a function you can find in the help, it is a built-in function that MATLAB uses internally:

>> which -all feature
built-in (undocumented)

Rename your m-file to something other than feature, or any other built-in function name. Check with "which -all" like I did above to make sure.

If you need more help, attach your image 'C:\Users\LENOVO\Desktop\Genuine\2\2.2.png' and your script (renamed m-file)with the paper clip icon.

It might be related to the plot line not ending correctly, and )); being on it's own line.
