The Fusion Energy Toolbox contains functions for:

Reaction rates for all major fusion reactions.
Power computations for all major fusion reactions.
Bremsstrahlung and synchrotron radiation functions.
Numerous plasma physics tools.
Magnet modeling tools including single loop, pancake wound magnets and flux conservation calculations
Heat transfer calculations
Balance of plant mass calculations.
Economic analysis of electricity generation.

Each module is self-documenting using Contents.m files - simply type help Module for help on that module. For example:

>> help FusionEngine

Functions have a standard help format that includes a description and a listing of the inputs and outputs of the function. This information is available in this API and through command-line and Matlab help. Demos list the functions used and provide a link to the published output.

>> help CrossSectionDemo
  Compare fusion cross-section methods

Most functions have built-in demos, so that you can run the function with no inputs and get a printout or plot demonstrating the function's capability. To search for particular functions, use the lookfor command with a keyword; this will search the first line of all the function and demo headers and return a list.

>> lookfor reaction
SigmaVPlot                     - Plot collision crosssections for D-D, D-T and D-He3 reactions.
DHe3Reaction                   - Computes the fraction of D going to each reaction.
FusionReaction                 - Finds products of fusion reactions.
FusionReactionDD               - Finds products of D+D fusion reactions. Reactions are specified below:
MaxwellianV                    - Computes Maxwellian thermonuclear reaction rates.
ReactionString                 - Create a string with a reaction.
SigmaV                         - Computes thermonuclear reaction reaction rates.
