​Basic concepts

In summary

• Before Starting 
• Fundamentals on I/O (Input/Output operations)​
• Basics on external procedures: functions, subroutines & modules 
• Characters & Strings: generating data files on demand
•  Arrays & File linking: using vectors and calling routines written in external files
• Integration of Ordinary Differential Equations
• The logistic growth model
• The generalized Lotka-Volterra Model 

​Advanced concepts

• Making your own library
• Interfacing Fortran with Python

All the coding techniques are introduced through examples. The section Basic Concepts covers the following fully coded examples: Monte Carlo evaluation of Greek Pi (different versions are discussed, check the links on the left). Numerical Integration of Ordinary Differential Equations (ODEs) with several explicit methods (implicit methods not discussed). In particular, I present the integration of the one dimensional simple harmonic oscillator, the logistic growth model and the generalized Lotka-Volterra model.   
(ALL the examples are self-compiling, i.e. no need to install more
​software than Fortran)
