Is there any workaround for the slow performance of path.m?

6 views (last 30 days)
I use Matlab on multiple machines and generally do not have write access to the directory where the path is saved (i.e. I cannot use the set path dialog or savepath.m to store my path for future sessions). Furthermore, even if I could do this, I want to automatically accomodate changes to the subfolders in my code directories at every startup.
For this reason I generate my path at every startup using a startup script. This script takes several minutes to run with virtually all the time being spent in path.m in the call to the built-in matlabpath function. In a recent startup test, 116.927 seconds were spent on 497 calls to matlabpath.
Is there any way of speeding this up?

can you show your code? Are you adding network paths?
I use addpath in the startup.m with no problems (runs very quickly, a few seconds)/
If your sub padirectorys are dynamic then use:
addpath ( genpath ( pwd ) )

building the string and then calling addpath worked. I'll mark your answer as correct since the comments contain the solution and you made the effort to answer, thanks.
