This blog post solves the following error:
"You can only call nargin/nargout from MATLAB function when using nargin. Error boiler_process (line 7) if (nargin <1), error('NNET:Arguments','Not enough arguments.') ; end error mapminmax (line 71) boiler_process"

1. Find mapminmax.m in C:\ProgramFiles\MATLAB\R2017a\toolbox\nnet\nnet\nnprocess and
   
   confirm that it is here. Let's proceed to the next step.

2. Find "Set Path" in the matlab homepage, click to enter
   

3. Add the path "C:\ProgramFiles\MATLAB\R2017a\toolbox\nnet\nnet\nnprocess" and save it.
   

4. Re-run the program and found that the problem has been resolved.

   This is the function that comes with matlab, the new version does not need to re-download the function, according to the above path can solve the problem.
