ReSpect v2.0

ReSpect 2.0 infers relaxation spectra from dynamic moduli.

This application extracts continuous and discrete relaxation spectra from dynamic viscoelastic measurements obtained from small-angle oscillatory shear experiments. This is a revised version of the original ReSpect which is hosted at http://www.mathworks.com/matlabcentral/fileexchange/40458-respect
It includes bug-fixes, new features, and algorithmic changes, described in the ReadMe.pdf file.

It can be used directly from the command line or graphical user interface (GUI). Functions and their tasks are described in detail in ReadMe.pdf file, which includes an example data file.

Run the command "contSpec()" or "discSpec()" to extract the continuous relaxation spectra (CRS) or discrete relaxation spectra (DRS), respectively. To access the GUI panel, run "specgui()".

The algorithms used are described in detail in the following paper:
