LAPACK++

LAPACK++ is a library written in C++ that provides object-oriented interfaces to the routines found in LAPACK (Linear Algebra PACKage). LAPACK is a widely-used, highly optimized FORTRAN library for numerical linear algebra. LAPACK++ aims to make LAPACK's functionality more accessible and easier to use within C++ programs by wrapping the original FORTRAN routines with C++ classes and functions that manage memory allocation, data types, and error handling in a more natural and less error-prone manner.

Key features of LAPACK++ generally include:

• Object-Oriented Interface: Provides C++ classes that represent matrices, vectors, and other linear algebra objects. These classes encapsulate the underlying data and provide methods for performing linear algebra operations.

• Memory Management: Automates memory allocation and deallocation, reducing the risk of memory leaks and other memory-related errors.

• Data Type Abstraction: Hides the details of the underlying data types used by LAPACK, allowing users to work with higher-level concepts.

• Error Handling: Implements C++ exception handling to report errors, providing a more robust error-handling mechanism compared to LAPACK's traditional error codes.

• Code Reusability: Facilitates code reuse by providing a well-defined interface to LAPACK routines.

LAPACK++ is often used in scientific computing, engineering, and other fields that require high-performance linear algebra computations. It allows developers to leverage the performance of LAPACK while benefiting from the features and convenience of the C++ programming language. The library typically focuses on dense matrix computations, covering areas such as solving linear systems, eigenvalue problems, and singular value decompositions. Alternatives to LAPACK++, depending on specific needs and project requirements, might include other C++ linear algebra libraries such as Eigen, Armadillo, or Blaze.
