Hi,

I need to find the eigenvectors of this matrix and get the following error:

> eigenvects(A);
 linalg:-eigenvects called with arguments: [[200, -96, 5, -4.4, 4.7, -12.6, -6.2], [-96, 320, 33.1, 6.8, 4.5, 7.4, -.3], [5, 33.1, z, -51.1, .8, -8.4, 7.6], [-4.4, 6.8, -51.1, 110, -76.6, -14.2, -67], [4.7, 4.5, .8, -76.6, 270, 78.3, -.1], [-12.6, 7.4, -8.4, -14.2, 78.3, 420, 38.3], [-6.2, -.3, 7.6, -67, -.1, 38.3, 230]]
 #(linalg:-eigenvects,7...

this is really 2 questions- the second being my attempted rectification of the first.

I have expressions in t for a vector. This vector by construction is always (and meticulously verified!!!) of the form [1,0,0....] when t = 0. when i do solve({final[1] = 1},{t}), I never get any solutions. I don't get the 'solutions may be lost' warning either, why not??? 

I thought, as the vector components are quite complex that this may be due to computational accuracy so attempted
