IRIS.inflate_region

[Cramer54]

For IRIS.inflate_region i am getting error while running main_trajectory_planning file like,

Error: [File: polytope.m Line: 2 Column: 8](matlab: opentoline('/MATLAB Drive/Alonso2017Multi/polytope.m',2,8))
Unable to find or import 'iris.inflate_region'. Imported names must end with '.*' or be fully qualified.

Error in [main_trajectory_planning>startxgoal](matlab:matlab.lang.internal.introspective.errorDocCallback('main_trajectory_planning>startxgoal', '/MATLAB Drive/Alonso2017Multi/main_trajectory_planning.m', 209)) ([line 209](matlab: opentoline('/MATLAB Drive/Alonso2017Multi/main_trajectory_planning.m',209,0)))
randpoly = polytope(obstacle.calc,randnode(i,:)',range);

Error in [main_trajectory_planning](matlab:matlab.lang.internal.introspective.errorDocCallback('main_trajectory_planning', '/MATLAB Drive/Alonso2017Multi/main_trajectory_planning.m', 36)) ([line 36](matlab: opentoline('/MATLAB Drive/Alonso2017Multi/main_trajectory_planning.m',36,0)))
[nodez, nodepoly, nodezinpoly]= startxgoal(nodez,nodepoly,nodezinpoly,[start;goal],config,obstcell,range,[lcx,lcy,lcz],[lmx,lmy,lmz];

For this how to solve the issue? i uploaded the CVX file, RVC tools
