The cause to this error message may be one of
- typo, you have misspelled the name of the function
- the function cannot be reached because it is not on the search path
- a function with that name exists on the search path, but it is not defined for the actual type of input. E.g.
>> max(cell(1,9))
Undefined function 'max' for input arguments of type 'cell'.
- the function does not exist on your system
Measures
- check spelling
- run the command which function_name -all. If which finds it run help function_name and read carefully
- if you think it is a function, which comes with Matlab, search for the function in the Matlab documentation
- search the file function_name.m with Windows Explorer or similar

Hello, please help me with the similar error as below:

The mfcc function was introduced in Audio Toolbox in release R2018a. Do you have this toolbox installed (check the output of the ver function if you're not sure) and are you using release R2018a or later?
