cobraMATLABsetpath

I want to test my installation after installing gurobi5, when I run initCobraToolbox, the error came up >> "Previously accessible file "C:\Program Files\MATLAB\R2013a\toolbox\cobra\external\addpath_recurse.m" is now inaccessible"

  • The "installation programs" of Matlab toolboxes (The MathWorks excluded) varies. You have to follow the specific instructions - if there are any ;-( &nbsp Installation of many toolboxes consists of two simple steps. Copy a bunch of m-files to a folder and add that folder to the path (and save the path).
  • I don't know anything specific about the installation procedures of these two toolboxes.
  • "type the savepath command" &nbsp has effect only if folders have been added by the "installation program" (your question hints that at least one required folder had not been added).
  • There is a little tool called Set Path. However, first see: What Is the MATLAB Search Path?. Use Set&nbspPath to find out whether the folders of the two toolboxes are in the path. Add folders if needed and remove the folder(s) of the old version of gurobi5 (hopefully the versions are in different folders). Test the functions and if it works save the path.
