Undefined function or variable 'rosbag_wrapper' #19

Open dlgusrl217 opened 5 years ago

I have downloaded the rosbag and have set the directory as MATLAB path. However, when I run the example code it gives the error as shown in the title. I also tried to move the files in the src folder to '~/Documents/MATLAB/' folder but I still see the same error. How can I tackle this issue?

I solved it by helping from a handsome boy. My errors display on the command window: `Undefined function or variable 'rosbag_wrapper'.

Error in ros.Bag (line 30) obj.handle = rosbag_wrapper(uint64(0), 'construct', 'ROSBagWrapper', obj.path);

Error in ros.Bag.load (line 19) obj = ros.Bag(path);

Error in calibrate_bundle (line 72) bag = ros.Bag.load(calibration_file);`

The key is the file of "rosbag_wrapper". I download the matlab_rosbag release version from "" I find the file "rosbag_wrapper.mexa64", and I use the "rosbag_wrapper.mexa64" to exchange the "rosbag_wrapper.mex" which is now in the my used path on matlab. Then it is ok.
