getpts MATLAB returns unrecognized function or variable 'getpts'-CodePudding

i'm trying to use getpts to choose points in the current figure using the mouse. However, when i run it, i'm getting the error "unrecognized function or variable 'getpts'."

Here's my code

for i=1:n
  im = imread([read_path 'IMG_' num2str(i t) '.jpg']); %Get image 
  figure
  imshow(im)
  [x,y] = getpts; %returns error
end

I'd appreciate the help!
