clc; clear all ;
file = 'cpc_rfe_v2.0_sa_dly.bin.20020101.nc' ;
lon = ncread(file,'lon') ;
lat = ncread(file,'lat') ;
RF = ncread(file,'RF') ;
%
path = [pwd filesep 'India State wise with telangana' filesep 'india27-11.shp'] ;
S = shaperead(path) ;
n = length(S) ;
pcolor(lon,lat,RF') ; shading interp ;
hold on
for i = 1%:n
x = S(i).X ; y = S(i).Y ;
rfi = interp2(lon,lat,RF',x,y) ;
end
Your next question is: 'I want data along the polygon, not along the boundary'. It is a project work and you expect everything online?

Dear @KSSV, what if the time is also given in the nc file i.e. nc data are in 3D...then how will we extract the data from .nc file according to given shapefile....

Example you can refer to for your convenience
W=shaperead('us_states.shp');
[data_cropped]=maskregion(lon,lat,data,W);
contourf(lon,lat,nanmean(data_cropped,3)','linecolor','none')
