Hello,

I can do the following in an external mupad session:

>> a:=matrix([[3,1,1],[1,0,2],[1,2,0]])

                               +-         -+
                               |  3, 1, 1  |
                               |           |
                               |  1, 0, 2  |
                               |           |
                               |  1, 2, 0  |
                               +-         -+
>> linalg::eigenvalues(a)

                                {-2, 1, 4}

But when I try to execute the same code inside a texmacs mupad session I 
got the following error:



  <\input|<\with|color|red>
    <with|mode|math|\<gg\>> <with|color|black|>
  </with>>
    linalg::eigenvalues(a)
  </input>

  <\output>
    Error: Wrong number of arguments [_not];

    during evaluation of 'piecewise::simplifyCondition'

    \;
  </output>


What's wrong?
