Finding border dataset having the same coastline with Coast.mat

Hi everybody,

I have compared "GADM data(version 3.6)" (blue) and "TM_WORLD_BORDERS_SIMPL-0.3" dataset from thematicmapping.org (green) with "coast.mat" in Matlab (red) and found differences.

I would like to ask whether there is any country border dataset having the same coastline as the Matlab's built-in coast.mat

Ardently looking forward to your reply! Thank you
