Eckart Inertias
23 May 2014   Contributor(s):: Bryan M. Wong
Eckart Inertias: calculates effective Eckart inertias for largeamplitude torsions. The Eckart inertias are obtained by solving a system of transcendental equations using the Powell dogleg method. Since this system is highly nonlinear, analytical Jacobians have been implemented in the dogleg...

Rappture setup in Ubuntu
22 Aug 2011   Contributor(s):: David Alberto Saenz
This is a short article about how to set up a functional copy of a rappture development environment simmilar to the workspace but in a local machine. This permits the user to make use of their own software licenses and develop rappture programs in matlab regardless of being outside the premises...

How to Make High Quality Plots in MATLAB
29 Jul 2011   Contributor(s):: Mehdi Salmani Jelodar
This presentation is a tutorial for plotting higher quality figures by Matlab. Basic elements of plots are introduced and the way to manipulate these elements by coding is explained. Tow methods for dual axis plotting is described. At the end an approach to print figures automatically (by...
