Image as function input

Hello

I have the SIFT_feature script from https://nl.mathworks.com/matlabcentral/fileexchange/50319-sift-feature-extreaction , but there is an image defined in the function itself.

In my script I'd like to use the SIFT_feature on defined images as shown below:

so in other words, I'd like to use the function SIFT_feature on my defined image E. This however, does not work since the function looks liks this:

Since I'm not that familiar with coding nor matlab, is there a way I can use an image defined in my script as input for the function? I experimented a bit with the SIFT_feature(img,origin) of the function but none of it seems to work.

Thanks in advance

Get rid of the "clear" in that function, after the tic statement.

That clear is deleting whatever you passed in for img and origin via the input argument list.
