How to Resize Images in ImageDatastore

I'm trying to resize several images from a file folder that I put into an ImageDatastore. The example code on Mathworks is the following:

imds.ReadFcn = @(loc)imresize(imread(loc),inputSize);

What is meant by loc? I assumed location but I'm getting errors. Or does this mean I need to make my own function and then call it in my script? Thank you.

'loc' is not the location, it is just a dummy parameter. To resize images in an ImageDatastore, assign a new read function to the ReadFcn property.

inputSize = [227 227];
imds.ReadFcn = @(loc)imresize(imread(loc),inputSize);
imshow(preview(imds));
