# Computational Physics (Lab) - M.Sc. Physics University of Delhi

## Semester: III Course Code: PH-CL502

### Manual by : Professor Shobhit Mahajan [>Profile<](http://people.du.ac.in/~sm/)
### Course Instructor : Professor Jyoti Rajput [>Profile<](http://du.ac.in/du/uploads/Faculty%20Profiles/Physics/Physics_Jyoti_Rajput.pdf)
As per our university syllabus, "This course is intended to be an Introduction to a **Programming Language C** as well as application for Numerical Analysis. The course would impart training in the structure of the programming language as well as train the students in using programs to numerically solve problems in various areas. In addition, it will also familiarize the students to the Unix environment."

We have been given a **[MANUAL](https://drive.google.com/file/d/10ZzmHsvMVDVspZUY6VBRm5HezVoqkNAQ/view?usp=sharing)** to practice the problems and here I'll commit the programs as I successfully compile and get the desired output. 
***This repository is under progress.***

### To Do List

## How to use GNUPLOT scripts?
It's better to write a gnuplot script with extension `filename.p`, rather than writing the commands on gnuplot terminal. This way we can save our gnuplot codes for future needs.

If you've saved a gnuplot script named `lissajous.p` in the current working directory: 
**For Linux user:** `gnuplot ./lissajous.p` 
**For Windows user:** `load "lissajous.p"`

*Note: If we use `load "lissajous.p"` in **gnuplot terminal**, it will work both in linux and windows.*

## Do you want to download all the codes at once?
### For Linux user:
All the linux distributers have git installed in their system so they simply paste the following code to get a local copy in your system. 
`git clone https://github.com/singhnir/DU-MSc-Lab-C-Prog.git`
### For Windows user:
Normally no windows has git preinstalled so previous command doesn't work on it but again you can download a zip copy of the codes clicking [**here**](https://github.com/singhnir/DU-MSc-Lab-C-Prog/archive/master.zip).

## Requirements
* Text Editor (Atom/Sublime...)
* GCC Compiler
* Gnuplot
