hej guys,

i have a 4x4 matrix, each element containing a complex function, depending on 'x' or whatever.

In fact i want to compute the 'eigenvalues' of the realpart of this matrix.

So far i tried:

assume(x,real):

then taking the real part of each matrix-element(function) on it's own, building a matrix again finally.

eigenvalues( ) gives me "Error, (in content/polynom) general case of floats not handled".

So yes, i appreciate any reply, thx in advance!!
