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
Any idea why that's happening? Note: I'm using the free trial version of Matlab
I'd appreciate the help!
From the docs, getpts is in the image processing toolbox.
This isn't always obvious, you can infer it from the docs link itself:
mathworks.com/help/images/ref/getpts.html
(where a built-in would be something like mathworks.com/help/matlab/ref/sum.html)
You can also see it's nested under the image processing toolbox in the side-bar on that page.
In your trial installation of MATLAB you likely don't have this toolbox. You might know from the install process, or you could check whether the toolbox folder exists in the installation directory, e.g.
