Greetings,

I'd like to introduce you to the "matexp" program. The matexp program solves Markov kinetic models for the NEURON simulator. It is faster and more accurate than the built-in "sparse" solver.

The matexp program uses a new method of integration. It characterizes the model at compile-time and stores that information in a specialized look-up table so that it is very fast at run-time. The method is limited to systems which are linear and time-invariant, and with less than three inputs.

Usage:
To use the matexp program, you need to provide:

• the ".mod" file to be solved,
• the name of the ".mod" file to write the solved equations to,
• the time step of integration "dt",
• the temperature of the simulation "c",
• a list of the inputs to the model,
  and the range of possible values for each input,
  and if the input is a chemical concentration, use the "--log" flag.

Example: The matexp program is free and open source, hosted on github: https://github.com/ctrl-z-9000-times/matexp

For more information about the new method of integration see: https://github.com/ctrl-z-9000-times/ma ... DETAILS.md

I hope you find this useful.
Sincerely, David McDougall
