The bug has been fixed in version 2.5.7 (Build 550). The ‘contains’ command was newly introduced in Matlab R2016b. For backward compatibility, version 2.5.7 (Build 550) is no longer using the ‘contains’ command.
actually my matlab version is 2018 and when i want to run the opensees from matlab and opensees navigator. it shows error and says cant be run opensees. i tried alot but again the same problem. hope someone help me
