Transfer Learning error when using @readFunctionTrain

I get the following error when trying to use the line [trainingDS.ReadFcn = @readFunctionTrain;] in transfer learning.

Error using matlab.io.datastore.ImageDatastore/subsasgn (line 196) Function readFunctionTrain does not exist.

How to solve this?I tried this code [trainingDS.ReadFcn = @(filename)readFunctionTrain(filename);] but it didn't solve the problem.
