Update of task #7793 (project relax): Percent Complete: 0% => 70% _______________________________________________________ Follow-up Comment #74: This is now complete for all analytical models. There is still room for improvement for numerical models. The problem with these, is the propagator that will evolve the magnetization with the matrix R for a delay tcp. This is matrix exponential calculation. We need to calculate the exact matrix exponential using the eigenvalue decomposition approach. matrix_exponential(R*tcp[i]) The matrix R contains all the contributions to the evolution, i.e. relaxation, exchange and chemical shift evolution. _______________________________________________________ Reply to this item at: <http://gna.org/task/?7793> _______________________________________________ Message sent via/by Gna! http://gna.org/
