solve.tridiag

a <code>tridiag</code> object: a square tridiagonal (all zeroes
	except for the main diagonal and the diagonals immediately above and
	below it) matrix containing the coefficients of the linear system.

a vector or matrix giving the right-hand side(s) of the
	linear system. If missing, <code>b</code> is taken to be an identity matrix
	and the function will return the inverse of <code>a</code>.

&#8230;

This function solves the equation <code>a %*% x = b</code> for <code>x</code>,
 where <code>a</code> is tridiagonal and <code>b</code> can be either a vector or a
 matrix.
