Free workspace script

SSTSLAB is an effective tool which provides you a simple Space Tether Simulation Laboratory. This tool is totally free.

Major Features:

1. It is a simulation tool for matlab/simulink, the current version is a beta version, it need more test work to make sure that the results are acceptable accurate.
   
2. Set the SSTSLAB folder as the current work path of MATLAB, which includes the following files: No. File Name Description
   • 1 SSTS_Contents.m Contents for SSTSLAB
   • 2 SSTS__lib_math.mdl Some math blocks for tether simulation
   • 3 SSTS__tether_dumbbell.mdl Dumbbell tether simulation
