Error reading license file on Mac

Hi, 

I am using Matlab 2019a and trying to install SNOPT. I got the following errors when run the runNPexamples, could anyone help with this? Thanks.

The first issue doesn't have anything to do with the license file.

The messages

"Warning: Name is nonexistent or not a directory: /Applications/util"

seem to indicate your path is not getting set correctly.

When you run 'runNPexamples', that script calls 'setpath' to add the appropriate directories to Matlab's path using pwd.  You should probably not run these scripts in /Applications/.

For the license error, you need to set the path in the correct format.  If you're on a Mac, you should use forward slashes and also included a forward slash at the beginning, e.g.,

setenv('SNOPT_LICENSE','/Users/yutongli/Downloads/snopt7.lic');

Hi Elizabeth, 

Thanks for the advise and now 'runNPexamples' works. However, I am using YALMIP with SNOPT, and when I run my YALMIP code the following errors show up, could you   please help me to see what is going wrong here? Which "SingleVehNavigate" is the name of my YALMIP matlab file.

>> SingleVehNavigate

Undefined function or variable 'snseti'.

Error in callsnopt (line 71)

snseti('Minimize',1)

Error in optimizer/subsref (line 326)

                eval(['output = ' self.model.solver.call '(self.model);']);

Error in optimizer/subsref (line 9)

    [varargout{1:nargout}] = subsref(self,subs);

Error in AdaptiveSeekController (line 125)

    uout = Controller(currentx,currentr,previousu,sin_sequence,cos_sequence,x_other,y_other);

Error in SingleVehNavigate (line 186)

            ctr = AdaptiveSeekController(vehCurrentState,vehCurrentTarget1,is,vehPreviousctr,

            ones(7,1), zeros(7,1), (vehicleContainer(2).currentPose(1))*ones(7,1),

            (vehicleContainer(2).currentPose(2))*ones(7,1));

You would have to ask the developers of YALMIP.  I don't know how it works.
