Programming / MATLAB - Plotting/Graphics
« on: August 23, 2016, 08:13:45 PM »
Dear all,

I have taken a session of MATLAB Graphics primer for the first year ME students in IISc. In this process, I have prepared some scripts which will familiarize one with wide range of plotting options available in MATLAB. The link below contains rar file having scripts, sample datasets and a pdf of presentation that I have made.

There is a script in the folder by name 'spatial mapping.m' which I feel is the most useful script for researchers working on geo-spatial domains. It is based on mapping toolbox. I have even provided sample data to run the script and see the output. I want to stress the fact that MATLAB has done wonderful job in generating spatial maps. Please feel free to use the codes in your research.

Models / Re: Help regarding data assimilation
« on: August 26, 2013, 01:00:44 AM »
There are various way of data assimilation e.g. Kalman filtering, 4d-Var, exponential filter etc.
Most popular of them is Kalman filtering. Simple Kalman filter applies to linear state systems.
For the non-linear case Extended for Ensemble Kalman filter is used.
I have attached my book, 'python in hydrology', there in section 10.6 I have briefly explained about the Kalman filtering.
The codes are in Python.
I hope it gives you a starting point.

I started reading Kalman filter from this link:
This also provide in simple language introduction about Kalman filter.
