Buffer problem Vector Data

Hi.

I try to add buffer to outside of this polygon shape file in Matlab.

But Matlab give me error "Undefined variable "data_in" or class "data_in.Y".

How to solve this?

[map_outline, att_map_outline] = ...
    shaperead('../data/addbuffertothis.shp','UseGeoCoords',true);
% Add buffer
km = 20; 
bufwidth = km2deg(km); % convert km to degrees of arc
[buffer.latb, buffer.lonb] = bufferm(data_in.Y, ...
 data_in.X, bufwidth, 'out', 20);

Hi,

I've never used these functions. However, It seems that data_in is not exist. Isn't it possible that data_in should be map_outline or att_map_outline?

ex) data_in.Y => map_outline.Y or data_in.Y => att_map_outline.Y
