A solution to the problem that the display of newff function in neural network cannot be converted from double to struct

I see a lot of solutions when I have this problem , But they are not very detailed , Check one question at a time , So write down how I solved it in detail .

1、 This problem is caused by a problem in the running path , Run the script , Type... In the command line window ‘path’, All running paths will be displayed ;

2、 In the input ‘cd’ Displays the current script run path ;

3、 It can be used ’user path‘ The command changes the working path to ：“userpath('D:\Matlab\matlab')”

4、 Last use ’save path‘ Command to save the path .

Generally, the data can run normally .

Another way is to , The path of neural network and LS-SVM Paths cannot exist at the same time , You can also install LS-SVM Delete the path .

Delete method ： Click on ：‘ Setting path in the home page ’—— Selected path delete .
