Today had been two part work. Initially, I did some Data Structures lessons from Udacity course. Then, at night, I tried to implement the Single objective optimisation method called fibonacci method using Fortran. There is some mistake that I need to correct. I will share the updated code tmw.Today I was able to cover a lot of stuff - mainly the exercises and some Gnuplot basics.
I’ve already made a blog post on the first exercise I worked on - Generate Logistic Map in Fortran. It was fun. Also, later I took a look at the solution available at the mooc’s repository.I had been following the MOOC “Scientific Computing with Fortran” for a week and currently doing the exercises. This is one of the assignments which has piqued my interests - Logistic map. Here’s a neat animation from Wikimedia for the same.
As Wikipedia states it, “The logistic map is a polynomial mapping (equivalently, recurrence relation) of degree 2, often cited as an archetypal example of how complex, chaotic behaviour can arise from very simple non-linear dynamical equations”.Today, I was introduced to I/O in Fortran. Its a little complex for seemingly simple task. But, its good to have all the bells and whistles known upfront. Here is a sample program on input output.

Basically, a procedure can be of two types
function subroutine Functions The functions are procedures which return a value which can either be
