hello i need to find the decomposition of this matrix

Matrix

but as you can see wolfram dose not solve it. it is strange because for example it can solve this one:

Matrix solvable

which contains parameters as the same above.

How can i make the decomposition of that matrix with any kind of software ?

I can solve this using Scilab Programming language? (which is open source) or R or Octave or things equivalent...

thank you

Well it can be done with MuPad, but it is not free.

My guess is that this matrix is too big for the free version of W/Alpha.

It can also be done with wxMaxima and it is free.
