 ### About
 
 **BLOCHUS** is a set of MATLAB<sup>TM</sup> tools, that allow some basic simulations of (S)NMR spin dynamics based on the Bloch equations. The Bloch equations are solved in the laboratory frame of reference with MATLABs built-in `ode45` solver. Because it was developed within the scope of a near surface SNMR project, its main features are the simulation of (1) pre-polarization switch-off ramps and (2) excitation pulses. The main front-end to the underlying simulation tools is a graphical user interface (GUI) that allows playing around with the different features and helps to understand the basic concepts of (S)NMR spin dynamics.
