Sample not working! :(

[rodrix385]

  I am running the sample code:
$documents = [
"The quick brown fox jumped over the lazy dog",
"hey diddle diddle, the cat and the fiddle",
"the cow jumped over the moon",
"the little dog laughed to see such fun",
"and the dish ran away with the spoon",
];

 $lsa = new LSA(4);
 $trans = $lsa->fitTransform($documents);
 
 $query = "the brown fox ran around the dog";
 $index = $lsa->query($query, $trans);
 echo $documents[$index], PHP_EOL;

...and I get
| Fatal error: Uncaught Exception: Error matrix dimension in E:\Dropbox\XAMPP7\htdocs\text-analysis\src\lib.php:19

I found your library on phpclasses.com, but I can't make it work :/
