Detailed Description

template<class Scalar>
class ExampleTridiagSerialLinearOp< Scalar >

Simple example subclass for serial tridiagonal matrices.

This subclass form a linear operator for tridiagonal matrices of the form:

\[ M= \left[\begin{array}{ccccc} d_{(1)} & u_{(1)} \\ l_{(1)} & d_{(2)} & u_{(2)} \\ & \ddots & \ddots & \ddots \\ & & l_{(n-2)} & d_{(n-1)} & u_{(n-1)} \\ & & & l_{(n-1)} & d_{(n)} \end{array}\right] \]

given the arrays lower[], diag[], and upper[] of dimension dim-1, dim and dim-1 respectively (see initialize()).

Note, this is just an example class and for the sake of simplified presentation the private members are listed first and in class declarations are used which are not a good idea in production code. However, in this case, they make the example code easier to read and maintaining encapsulation and a well defined interface are unnecessary here.

Initialize given lower, diagonal and upper arrays of data.

Parameters:
dim [in] Dimension of this matrix (must be >= 2).
lower [in] Array (length dim-1) of the lower diagonal elements
diag [in] Array (length dim) of the central diagonal elements
upper [in] Array (length dim-1) of the upper diagonal elements
Preconditions:
  • dim >= 2

Postconditions:
