Hey Emimal,
I understand that you are facing an error with the “readLabel” function while creating a “fileDatastore” type object to store the “Japanese vowels data” folder.
The error message shown points out that the function “readLabel” is undefined for input arguments of type 'string'. This tells that MATLAB is not able to locate the custom “read” function (readLabel) you are trying to use for your “fileDatastore”.
I would suggest you to recheck if you have created a function called “readLabel” in the same folder as your current script or the folder containing the function is added to the MATLAB path. Also, ensure that the “readLabel” function can accept arguments of the type “string”.
You can refer to the “@fcn” input argument section in following documentation to know more about defining a custom read function for “fileDatastore”.
I hope this helps!
