评论： Walter Roberson 2018-8-6

When I use

   ds = mahal([X Y], [X Y]); 
   Undefined function 'mahal' for input arguments of type 'double'
   or
   ds = mahal(double([X Y]), double([X Y]));
   Undefined function 'mahal' for input arguments of type 'double'.

Can someone help me?

The X and Y are two list. X =

And Y =

not working after I follow your instruction to reset everything. Undefined function 'mahal' for input arguments of type 'double'.

The mahal function is in the Statistics and Machine Learning Toolbox (in older releases, just Statistics Toolbox).

Do you have this installed? You can check by typing "ver" at the Command Window and seeing if it appears.

Hmmm... I wonder why it can't find the function then. First, try typing the following command:

>> which -all mahal

... and seeing if anything comes up. If it doesn't, it may be likely that something went wrong with where MATLAB is looking for functions. You could try resetting the default MATLAB path and toolbox cache with these commands,

>> restoredefaultpath
>> rehash toolboxcache

Let's see if that works.

Not working, should I reinstall it?

>> which -all mahal /Applications/MATLAB_R2015a.app/toolbox/stats/stats/mahal.m % Has no license available /Applications/MATLAB_R2015a.app/toolbox/stats/stats/@gmdistribution/mahal.m % gmdistribution method, Has no license available >> restoredefaultpath >> rehash toolboxcache >> LACS( 'test_in.txt', 'test_out.txt' ) Undefined function 'mahal' for input arguments of type 'double'.

Error in ord>pf (line 114) ds = mahal([X Y], [X Y]);

Error in ord>findoffset (line 100) offset = pf(tmp(:, Nn+1), tmp(:, Nn+2), x, tmp(:, 1:2), out_name, ths(x-1));

Error in ord (line 49) offset = findoffset(tmp, x+1, out_name, pH);

Error in LACS (line 35) ca = ord(filename, 2, out_name);

See how when you typed in that "which -all" command you got this:

>> which -all mahal 
/Applications/MATLAB_R2015a.app/toolbox/stats/stats/mahal.m % Has no license available
/Applications/MATLAB_R2015a.app/toolbox/stats/stats/@gmdistribution/mahal.m % gmdistribution method, Has no license available

I would contact your license administrator or call MathWorks customer support to figure this out. I know absolutely nothing about licensing, but it seems like something is either wrong or expired.

Right, the software is installed but you have no current valid license for it. This includes the case where you are using a license server and it has run out of licenses for that toolbox, but you would normally have seen other relevant messages as well in the license server case.
