Todo List Class gslmm::cholesky_decomposition< double > Implement gsl_linalg_cholesky_decomp_unit Class gslmm::function_base< Value, Argument, Derive, Error, Scale > I'm not sure I really want this class, as must of the interfaces will deal with template arguments, rather than sub-classing of a specific base class. Class gslmm::lq_decomposition< double > gsl_linalg_L_solve_T Class gslmm::permutation Should I leave in the put-to operator? Class gslmm::qr_decomposition_pivot< double > implement gsl_linalg_QR_update Class vector Make I/O member functions. make outer product member function. Perhaps the view copy constructor could be private?. What about the assignment operator in the face of non-RVO Group blas Implement the rest of the tests of these functions and structures. Use these function in the matrix and vector modules for matrix-vector and matrix-matrix products. Group constant Implement these classes. These should be implemented as templated structures with static data members. Group differentiation Implement these classes. Group eigen Implement these classes. Group fit Check these classes Implement test-suite Group fourier Implement these classes. These are a bit tricky, as they used packed complex numbers rather than arrays of complex numbers. I guess a special class is called for. Group hankel Implement these classes. Group integration Implement these classes. Group interpolation Implement these classes. Group linear Have implemented LU-decompostion LQ-decompostion PTLQ-decompostion QR-decompostion QRPT-decompostion SV-decompostion Cholesky-decompostion Group minimization Implement these classes. Should be implemented as templates. May need to do something to the function structures. Group montecarlo Implement these classes. Group ordinary Implement these classes. Group root Implement these classes. Group series Implement these classes. Group sort Implement these classes. Group special Implement these classes. Member gslmm::operator * (const matrix_manip< T > lhs, const matrix_manip< T > rhs) Implement some more clever stuff based on the manipulator. Group vectormatrix Use the BLAS functions to implement matrix-vector and matrix-matrix multiplication, as well as possibly some other stuff.
