Matlab vs Mathematica Eigenvectors Calculation

[Alexei]

It appears that Matlab and Mathematica are calculating eigenvectors in their own way that results do not match; what methods do exist in Mathematica to control presentation of eigenvectors?

why should they match?

Note For eig(A), the eigenvectors are scaled so that the norm of each is 1.0. For eig(A,B), eig(A,'nobalance'), and eig(A,B,flag), the eigenvectors are not normalized.
Also note that if A is symmetric, eig(A,'nobalance') ignores the nobalance option since A is already balanced.

Both tools produce values conforming to the A.v=l.v equation; however, I need a way for Mathematica to produce the numerical answer not using symbolic notation with complex numbers, if possible. Also, does it produce normalized eigenvectors?
