eigen.sym R Documentation
Spectral decomposition of a matrix
Description
Computes eigenvalues and eigenvectors of real symmetric matrices.
Usage
eigen.sym(x)
Arguments
x
A real symmetric matrix.
Details
This is to use the LAPACK routine 'DSYEVR' to perform spectral decomposition.
Value
values
a vector containing the eigenvalues of x, sorted in decreasing order.
vectors
a matrix whose columns contain the eigenvectors of x, corresponding to eigenvalues.
Note
Warning: symmetry is not checked by the program!
See Also
eigen for more information.
