Program inside markers add tags to the geographical position, multiple locations with a vertical bar | segmentation, why when I set to latitude and longitude for numerical, such as' 119.33588, 32.3221 | 119.3323, 32.6644 can mark two points at the same time, but the use of variable [L1 B1] | [L2 B2] not, personally, I guess it should be in the matlab | defaults to the operator, is excuse me this reason? How to solve this problem? I want to use variable said multiple locations, a great god give advice or comments!
