@Markiyan Hirnyk Excellent, thank you! Much appreciated!!

Hi Markiyan,

Thanks for the suggestion. I had read through the solve help file but I didnt realise there was an 'allvalues' func. Thank you, that was very helpful.

I was hopping to express the roots of the quartic: (s+T1)(s+T2)(s^2+2ζωn+ωn^2)

in the form of

T1 = ...

T2 = ...

..

However, perhaps this isnt possible afterall. At the moment the output of 'allvalues' exceeds maples character limit so I am unable to display the result. Is there by chance an alternative approach by which one might tackle the problem?

Patrick, the 'long call' worked a charm.

Thanks to all for your assitance.

Cheers!!

Thank you both kindly for your response. Having corrected the function calls within the worksheet it would notappear to be the source of the problem.

for example, running:

> with(LinearAlgebra);

> A := Matrix(3, 3, [[s*m-X[u], -s*X[wdot]+X[w], -(X[q]-m*W[e])*s+m*g*theta[e]], [-Z[u], -(Z[wdot]-m)*s-Z[w], -(Z[q]+m*U[e])*s+m*g*sin(theta[e])], [-M[u], -M[wdot]-M[w], I[y]*s^2-M[q]*s]]);

> B := Vector([X[eta], Z[eta], M[eta]]);

For simple commands such as

> Mutiply(Adjoint(A)/Determinant(A), b);

and

> Multiply(A, b);

I still recieve the outpus

If possible I would like to obtain the solution itself.

Many thanks for you assitance.
