I have a point shp file 'ULS170527All.shp' with eleven attributes. The attributes are shown as follows in ArcGIS:

Then, I used the following expression to read it:

Tree = shaperead('ULS170527All.shp');

The following image shows the field names and data of the 'Tree' variable:

Is this a bug of MATLAB?

Did anyone have the similar problem?

The code for shaperead contains,

        reservedNames = {'Geometry', 'X', 'Y', 'Lat', 'Lon', ...
                 'BoundingBox', 'Height', 'INDEX'};

I have not yet been able to figure out why Height and INDEX are reserved, but we can see from the code that it is deliberate.

Thank you very much for your answer. So we cannot use any of names listed in the code, right? I just found that the shapeinfo function can read all of attribute names correctly, so I can fix it using the result of shapeinfo.
