Normalising datasets in Matlab
13 Aug 2013 | Contributor(s):: Tom D Pering
A very brief and simple Matlab function for normalising a dataset. I have often wondered why Matlab doesn't include this in the main package, so here is a simple code to achieve this.

Matlab Codes for Volcanology - Stokes Rise Calculations for Bubbles
09 Aug 2013 | Contributor(s):: Tom D Pering
A series of Matlab codes for the determination of the rise speed of stokes bubbles at a single point (i.e. at a given depth and set radius) and over a range of depths. The aim of these files is to allow the calculation of rise speed given the overall bubble composition and the proportions or mass...
