Summary of techniques

The following techniques have been used in the design of the Matrix class library:

• Inheritance to expand functionality, e.g. SubMatrix.
• Flags to provide similar, yet different functionality from the same classes, e.g. the TriangularSolverComponent and MatrixHandler classes, with flags initialized depending on their place in the actual class hierarchy.
• Central collection of common data storage, and operations on the data in the Matrixscope class.
• Implicit type conversion to handle a number of operations, e.g. factorization.
• Delayed evaluation of outer product expressions.
• All expressions view the matrices as submatrices.
