Simple example subclass for serial tridiagonal matrices.
This subclass form a linear operator for tridiagonal matrices of the form:
![\[ M= \left[\begin{array}{ccccc} d_{(1)} & u_{(1)} \\ l_{(1)} & d_{(2)} & u_{(2)} \\ & \ddots & \ddots & \ddots \\ & & l_{(n-2)} & d_{(n-1)} & u_{(n-1)} \\ & & & l_{(n-1)} & d_{(n)} \end{array}\right] \]](form_64.png)
given the arrays lower[], diag[], and upper[] of dimension dim-1, dim and dim-1 respectively (see initialize()).
