### What this code does

The code packages linked below are used to compute ultimate basis-set in realistic body models and then use these basis-sets to compute the ultimate SNR. The ultimate basis-set code package contains the Matlab scripts and MARIE routines that are required to compute basis-set in non-uniform body models as described in the citations above. MARIE is a freely available ultra-fast volume integral solver. You may download it separately or as part of the basis-set package linked below. Downloading the latest version of MARIE will ensure that you are using the fastest/lastest/most bug-free version of the software, however I do not guarantee that it will interface perfectly with the ultimate basis-set scripts. The MARIE routines included in the package linked below may be a bit "old", but they interface with the ultimate basis-scripts without errors.

### Computer requirements

Ultimate basis-set computations are usually long (at least 24 hours for a simple model to a few days for complex models or high frequencies -- see the citations above). Therefore to run this code, I recommend the following computer requirements (these are a not strictly speaking required... You may try the simulation on a slower computer and pray that it works or simply wait longer!!):

- RAM: At least 64 GB
- CPUs: At least 8 cores
- GPU: A GPU is required for this application, which is used to accelerate MARIE. Without the GPU, computation times will really become large for basis-set with a 2000 basis vectors and more. I recommend using at least a Tesla K20.

### Download files

The ultimate basis-set computation code can be downloaded here.

### Instructions

#### Ultimate basis-set calculation

To run an example of ultimate basis-set, download this folder and unzip it.

#### Steady state simulations

To run a simple example of the steady-state simulation, go to the TEST_SteadyState/ folder and run "TEST_SS.m". Again, the way to run the code should be straightforward. The input to the steady-state function are similar to the input to the transient solve function, except obviously the duration is not needed.
