Four separate example scripts are given in the top directory; these may be used for reproducing the four experiments presented in **this paper**.

* **Experiment 1** ( `expt1_steady_state_GRE.m`)
* **Test 1** ( `test1_steady_state_GRE.m`)

Compares the steady-state found by EPG-X calculation with direct steady-state calculations for which solutions exist. Examples are given for SPGR and bSSFP sequences.
- The transient phase of SPGR is considered
- SPGR signal vs RF spoiling phase increment also included


* **Experiment 2** ( `expt2_multislice_TSE.m`)
* **Test 2** (`test2_transient_GRE.m`)

Compares single slice and multi-slice TSE for a system with MT effects. In the multi-slice case the excitation of other slices creates off-resonant saturation of the bound pool magnetization in the local slice, leading to signal attenuation when compared with the single slice case.
Simulates balanced SSFP and SPGR sequences with variable flip angles following an inversion pulse, for a system with MT effects. This type of sequence has been proposed for use in Magnetic Resonance Fingerprinting (MRF) - the experiment explores the possible influence of MT on this method.

* **Experiment 3** (`expt3_transient_GRE.m`)
* **Test 3** (`test3_multicomponent_CPMG.m`)

Simulates balanced SSFP and SPGR sequences with variable flip angles following an inversion pulse, for a system with MT effects. This type of sequence has been proposed for use in Magnetic Resonance Fingerprinting (MRF) - the experiment explores the possible influence of MT on this method.
Simulates multiecho CPMG sequence for two compartment system coupled by chemical exchange (follows Bloch-McConnell equations). This type of measurement is used for multicomponent T2 estimation - the simulation explores how exchange can influence the estimated parameters

* **Experiment 4** (`expt4_multicomponent_CPMG.m`)

Simulates multiecho CPMG sequence for two compartment system coupled by chemical exchange (follows Bloch-McConnell equations). This type of measurement is used for multicomponent T2 estimation - the simulation explores how exchange can influence the estimated parameters
* **Test 4** ( `test4_multislice_TSE.m`)

Compares single slice and multi-slice TSE for a system with MT effects. In the multi-slice case the excitation of other slices creates off-resonant saturation of the bound pool magnetization in the local slice, leading to signal attenuation when compared with the single slice case.
