Hello So-mang Kim,
As per my understanding,you are encountering error while trying to open Neural Network Fitting application from MATLAB.
To do this, simply execute the following command:
nftool
Please note that this command does not require any arguments.
For more information on Neural Network Fitting application, consider going through the following resources:
