In addition to neural modeling, it provides a simple, general-purpose interface for numerically integrating all models supported by MATLAB's built-in solvers for ordinary differential equations.

DynaSim's higher-level specification, described below, easily scales to arbitrarily complex population models and networks of interconnected populations (Figure (Figure4), 4), and does not require significant “boilerplate” code for even very large networks.

It facilitates rapid prototyping of neural models by enabling networks of neurons with one or more compartments to be specified by any combination of: (1) equations with conventional mathematical notation (Figures (Figures1, 1, ,2), 2), similar to XPP (Ermentrout, 2002) and the Brian simulator (Goodman and Brette, 2008), (2) built-in MATLAB functions, and (3) predefined, mechanistically-meaningful model objects (Figures (Figures3, 3, ,4), 4), similar to objects in Brian, mechanisms in NEURON (Hines and Carnevale, 1997), and nodes/connections in NEST (Gewaltig and Diesmann, 2007). It enables researchers to focus on model details instead of implementation, while making it easy to share and explore models with the rest of the community. This tool promises to reduce barriers for investigating dynamics in large neural models, facilitate collaborative modeling, and complement other tools being developed in the neuroinformatics community.ĭynaSim ( ) is a MATLAB (MATLAB, 2017) and GNU Octave (Eaton et al., 2016) toolbox developed for rapid prototyping of large neural models and batch simulation management. The design of DynaSim incorporates a novel schema for model specification to facilitate future interoperability with other specifications (e.g., NeuroML, SBML), simulators (e.g., NEURON, Brian, NEST), and web-based applications (e.g., Geppetto) outside MATLAB.

It also includes a graphical user interface (DynaSim GUI) that supports full functionality without requiring user programming. DynaSim also includes a large set of features that simplify exploring model dynamics over parameter spaces, running simulations in parallel using both multicore processors and high-performance computer clusters, and analyzing and plotting large numbers of simulated data sets in parallel. The higher-level specification supports arbitrarily complex population models and networks of interconnected populations. Models can be specified by equations directly (similar to XPP or the Brian simulator) or by lists of predefined or custom model components. It is designed to speed up and simplify the process of generating, sharing, and exploring network models of neurons with one or more compartments. * Presents programming concepts and MATLAB built-in functions side-by-side, giving students the ability to program efficiently and exploit the power of MATLAB to solve problems.DynaSim is an open-source MATLAB/GNU Octave toolbox for rapid prototyping of neural models and batch simulation management.

In-depth coverage is given to input/output, a topic that is fundamental to many engineering applications. It starts with programming concepts such as variables, assignments, input/output, and selection statements, moves onto loops and then solves problems using both the 'programming concept' and the 'power of MATLAB' side-by-side. Assuming no knowledge of programming, this book presents both programming concepts and MATLAB's built-in functions, providing a perfect platform for exploiting MATLAB's extensive capabilities for tackling engineering problems.
