https://www.mathworks.com/help/nnet/ref/augmentedimagedatastore.html was new in R2017b, whereas alexnet was new in R2017a. If you are using R2017a you would not have augmentedImageDatastore

I am getting the same error. I am using matlab 2017b and when I try to resize images as:
newImds = augmentedImageDatastore(outputSize,imds);
I get error as: Undefined function or variable 'augmentedImageDatastore'.
Could somebody please help with any solution on how to solve this ?

I installed R2018a and augmentedImageDatastore function worked. I think this function was introduced only in R2018a as it says in the last line of the documentation page. https://www.mathworks.com/help/nnet/ref/augmentedimagedatastore.html

mingwei wen: if you are using before R2018a you should probably upgrade. There is a way to construct an image data store in a couple of releases before that, by constructing a data store and setting the options to make it an image data store, but in those older releases not many functions supported those kinds of data stores.
