The RefSymmSCMatrix class is a smart pointer to an SCSymmSCMatrix specialization.

Initializes the matrix pointer to 0. The reference must be initialized before it is used.

Create a vector with dimension d by d. The data values are undefined.

RefSymmSCMatrix sc::RefSymmSCMatrix::block (int i) const

If this matrix is blocked return block i. Otherwise return this as block 0.

Sets eigvals to the eigenvalues and eigvecs to the eigenvalues and eigenvectors of the referenced matrix. The result satisfies eigvecs * eigvals * eigvecs.t() = (*this).

If this matrix is blocked return the number of blocks. Otherwise return 1.

Solves this x = v. Overwrites v with x.
