Terminology

The terms and conventions the code and these pages use.

Signal model

A signal model is a Simulator subclass: a handler per kind of event, and a layout of one repetition (Signal model). It is the only thing a sequence has to supply; differentiation, device placement, parameter estimation, model-based reconstruction and sequence design are written once against that interface.

Units

Units are public at the edges and internal underneath. A caller writes milliseconds, degrees and Hz; a description timestamps in microseconds and carries radians. Convert at the boundary, and name the unit in the identifier (duration_s, flip_rad, t1_ms) rather than in a comment beside it.

Course and Applications

The gallery has two kinds of page. A Course lesson is one of the five numbered pages read in order, from a shipped simulator to a signal model and an operator of your own. An Application is a complete worked example built on the Course, which stands alone and names the lessons it assumes.
