评论： SK 2020-4-22

Hello,

I enter this simple code (example given by matlab documentation) :

>> load examgrades;

>> x = grades(:,1);

>> y = grades(:,2);

>> h = vartest2(x,y,'Tail','right')

But I have this error message :

Unable to resolve the name statslib.internal.parseArgs.

Error in internal.stats.parseArgs (line 42)

[varargout{1:nargout}] = statslib.internal.parseArgs(pnames,dflts,varargin{:});

Error in ttest (line 104)

internal.stats.parseArgs(okargs,defaults,varargin{:});

It's ok when I write just : h = vartest2(x,y)

I'can't add name-value pair arguments.

I don't understant this error message. have already used this function with my free trial license and I never had a problem before.

Thanks for your solution !

在 MATLAB Online 中打开

Hello SK,

I just tried your code and didn't face any problems.

load examgrades;
x = grades(:,1);
y = grades(:,2);
h = vartest2(x,y,'Tail','right')

I am using R2019b, can you tell me which version do you have?

You can also try to run this from matlab root directory. To go to root, run cd(matlabroot)

Thanks,

Deepak

Are you running this code line by line in command prompt? I think that could be the problem.

Can you try to run this using a script file? Or use live script as given in the example itself. It should run fine

SK 2020-4-22

Yes I have already tried line by line and with a script.

I test an another script and I had the same problem (linear fit):

Unable to resolve the name statslib.internal.parseArgs.

Error in internal.stats.parseArgs (line 42)

[varargout{1:nargout}] = statslib.internal.parseArgs(pnames,dflts,varargin{:});

Error in LinearModel.fit (line 937)

internal.stats.parseArgs(paramNames, paramDflts, otherArgs{:});

Error in fitlm (line 121)

model = LinearModel.fit(X,varargin{:});

Error in reglin (line 21)

mdl=fitlm(x,y);

I don't understand !!!! Should I reinstall matlab ?
