Angular Momentum Worksheet

This is a set of functions that allows to test the weak form market efficiency and thus the predictability of the time series returns through various tests: direct and indirect test.The direct tests are the two versions (individual and joint)of the variance ratio of Lo and MacKinlay (1988).The...

Slow and dirty way to save a simple structure to an Excel file with xlswrite. I did it to solve a urgent problem for a friend. Lots of improvements possible, I'm sure.STRUC2XLS (FILE,S) writes the contents of structure S to a excel file named FILE. The name of the worksheet and the starting row...

It uses the Pierson-Moskowitz spectrum for the frequency/wave-number dependency and four different types of angular spreading like cosinus-squared, Mitsuyasu, Hasselmann and none.

The Ejs Phase Space Plotter model displays the dynamics of an ensemble of pendula or simple harmonic oscillators in phase space (velocity versus position). Friction is initially set to zero but can be changed via a textbox as can the number of elements in the ensemble. For the pendulum ensemble,...
