I am having trouble calling the following code:

% Load image and convert image to array

img = imread(imgPath);

% Get the size of the image

imageSize = size(img);

It crashes at the second line, with the error:

Array indices must be positive integers or logical values.

Error in build_vocabulary (line 27)

imageSize = size(img);

I've tried checking the path is correct, it is.

I've tried isempty() on img, it's not

I've tried resaving the image to the project folder, it looks fine.

I've tried checking the format it's in, it's uint8

I've tried disp(img) and it says:

(:,:,1) =

Columns 1 through 23

208 209 210 212 213 214 214 214 213 213 213 214 214 214 215 215 217 217 217 217 217 217 217

... for many more lines

Please can someone tell me what I'm doing wrong

You have a variable called "size".

If this is a script, do

clear size

and then run the script again.

If this is a function, rename your size variable to another name that's not a function's name.

Thank you for the explanation - though as a matlab newbie most of that still goes over my head even when you explain it to me! Like what you've said makes sense but I couldn't apply it on my own.

I'm used to the compiler telling me what's wrong, like when I defined the variable 'size' it might have shown me a warning saying that it overlaps a function name from my project.

Anyway thanks again!
