我正在尝试将Shapefile中与国家/地区对应的矢量数据转换为0.1度分辨率的栅格， 为此，我正在使用
vec2mtx and imbedm
功能。这是我正在尝试的方法，但是MatLab抛出错误。
%%%%here states is a shapefile of the world.
states=shaperead('Z:\shpfiles\TM_WORLD_BORDERS_SIMPL-0.3.shp');
lat = [states.Y]; %%lat and lon are of size 30032x1 each and there are 246 countries in the shapefile
lon = [states.X];
%%%% I convert it to a matrix of 0.1 degree resolution
[Z, R] = vec2mtx(lat, lon, ...
10, [-90 90], [-180 180], 'filled');
%%%% The same shapefile has an attribute of literacy rate for each country, to convert the literacy rate at 0.1 degree resolution, keeping the
%%%% value constant within each country,
Z = imbedm(lat, lon, [states.Lit2005], Z, R)
%%%%%THE ERROR
Error using imbedm (line 53)
Function imbedm expected its LAT, LON, and VALUE inputs to have the same size.
