can the mp tool be used to solve positive solutions of a linear system (lsqnonneg in MATLAB)?

We have just included lsqnonneg into the newest toolbox version. Please re-download it from our webpage. Examples:

>> mp.Digits(34);
>> C = mp('[0.0372 0.2869;  0.6861  0.7071; 0.6233  0.6245; 0.6344 0.6170]');
>> d = mp('[0.8587; 0.1781; 0.0747; 0.8405]');
>> x = lsqnonneg(C,d)

x = 

                                           0    
        0.6929343971302933831938176511663673

>> mp.Digits(100);
>> C = mp('[0.0372 0.2869;  0.6861  0.7071; 0.6233  0.6245; 0.6344 0.6170]');
>> d = mp('[0.8587; 0.1781; 0.0747; 0.8405]');
>> x = lsqnonneg(C,d)

x = 

                                                                                  0    
        0.6929343971302933831938176511663670971062510...868165705163788676921766095

Options and multiple outputs are also supported.

Let me know how it works for your problem.

Thank you 

The new version works with the lsqnonneg but doesn't acccept my licence. What i have to do? please
