The Low-Field NMR toolbox for MATLAB



Henrik T. Pedersen, Rasmus Bro & Søren B. Engelsen



The “Low-Field NMR toolbox” contains programs that have been used in published work. Currently the toolbox contains 1) a routine for exponential fitting using a simplex algorithm for the non-linear time constants and a least squares calculation of the linear amplitudes inside the function evaluation call, 2) a routine to phase rotate quadrature FID or CPMG data called “Principal Phase Correction” and 3) an algorithm to solve the SLICING problem based on the algorithms in the N-way Toolbox v. 2.00. The Low-Field NMR toolbox is self-contained.
