matrix2 diagonalizesymmetric(matrix2 symmat, vector2 &diag)

matrix3 diagonalizesymmetric(matrix3 symmat, vector &diag)

matrix diagonalizesymmetric(matrix symmat, vector4 &diag)

Returns the orthogonal matrix which, combined with the diagonal matrix implicit in the second argument, will form the original symmetric matrix.

This can be useful for analyzing the result of summing a series of outerproduct updates.

symmat

The symmetric matrix to diagonalize.

diag

The diagonal elements of the diagonal matrix.
