This study introduces MATLAB functions for analyzing biochemical networks using deterministic and stochastic modeling approaches. The tools facilitate the simulation of ordinary differential equations and chemical master equations for systems biology research.

Area of Science:

  • Systems Biology
  • Computational Biology
  • Biochemical Network Analysis

Background:

  • Complex biochemical networks are crucial for understanding cellular processes.
  • Existing modeling frameworks include deterministic (ordinary differential equations) and stochastic (chemical master equations) approaches.
  • MATLAB is a widely adopted environment for scientific computation and modeling.

Purpose of the Study:

  • To present a collection of MATLAB functions for deterministic and stochastic modeling of biochemical networks.
  • To provide tools for constructing and solving ordinary differential equations and simulating chemical master equations.
  • To encourage experimentation with systems biology models using accessible MATLAB code.

Main Methods:

  • Development of MATLAB functions for deterministic simulation via ordinary differential equations.
