-Auryn is a set of lightweight classes combined with some examples of how to use them. The power of the framework derives from its speed and extensibility if you do not hesitate to write a few lines of C++ code+====== Compiling the library ======

 +To get started you need to download and compile Auryn. See [[:quick start]] or [[CompileAuryn]] for instructions.

 Auryn was specifically designed to study synaptic plasticity. To see plasticity in action you can monitor single synaptic weights or groups of them using a [[WeightMonitor]] object. If you are only interested in let's say the mean weight change in one of the plastic [[Connection]] objects your defined (i.e. the mean weight between two neuronal populations in your simulation), you can use [[WeightStatsMonitor]]. You will find other Monitor classes in the Auryn ''src'' directory (see also the [[http://www.fzenke.net/auryn/doxygen/current/annotated.html|Class index]]; Monitor classes should be suffixes with ''Monitor'') or you can write your own for your specific needs.  Auryn was specifically designed to study synaptic plasticity.
