Error from using lsqnonneg with sparse matrix input(s).  

>> [X] = lsqnonneg (sparse([1 2;2 1]), [1 0]');
error: matrix dimension with negative or zero size
error: called from
    lsqnonneg at line 122 column 12

No error for full matrix inputs: 

>> [X] = lsqnonneg (full([1 2;2 1]), [1 0]');
>>

Thanks.
