LCS MATLAB Kit Version 2.3 (w/ inertial particle modelling!) [.ZIP; 405 KB]
This MATLAB software package improves the interpolation scheme used in Version 1.0, optimizes the algorithm for significantly reduced computational time, and enables the calculation of FTLE fields for inertial particles using a linearized Maxey-Riley model. See Shadden et al. (2006), Peng and Dabiri (2009), and the LCS Online Tutorial for background and technical details regarding Lagrangian coherent structures.



LCS MATLAB Kit Version 1.0 [.ZIP; 166 KB]
This MATLAB software package enables the user to input a time-series of velocity field data (e.g., DPIV measurements or CFD calculations) and compute the corresponding finite-time Lyapunov exponent (FTLE) fields, from which Lagrangian Coherent Structures (LCS) such as vortices and fluid transport barriers can be identified.
