As nouns the difference between eigenvalue and eigenstructure

is that eigenvalue is (linear algebra) a scalar, $\backslash lambda\backslash !$, such that there exists a vector $x$ (the corresponding eigenvector) for which the image of $x$ under a given linear operator $\backslash rm\; a\backslash !$ is equal to the image of $x$ under multiplication by $\backslash lambda$; ie $\{\backslash rm\; a\}\; x\; =\; \backslash lambda\; x\backslash !$ while eigenstructure is (mathematics) the set of eigenvalues of a matrix.
