Eigenvalues Calculator of a Real Symmetric Matrix -- updated

This program computes the eigenvalues of a real symmetric matrix:

(i) the program accepts a full matrix, A, as input,

(ii) tests it for symmetry and, if symmetry is confirmed,

(iii) calculates the eigenvalues of A.

The routine imposes no restriction on the size of A. The only restriction on A is that its coefficients be real; this program does not handle complex coefficients.

The underlying routine is a severely-edited translation of the EISPACK sub-program RS.F.

A couple aspects of this version of the routine should be highlighted:

(i) only eigenvalues are computed; eigenvectors are not.

(ii) the main program accepts input of a full symmetric matrix and tests it for symmetry before passing the matrix into the sub-routine that computes the eigenvalues. In other words, if only half the matrix is input, the program will output an error message indicating non-symmetry and halt execution. If a user would like to enter only half the matrix, the code could be edited--assuming the user knows JavaScript. (C++ code for this program is also available, posted on GitHub.)
