S = shaperead('file') is a structure. Use plot(S(i).X,S(i).Y) ,,i will be from 1:length(S). Varies according to your state. I suggest you to use pcolor or surf rather imagesc for plotting.

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) ;
x = zeros(n,1) ; y =zeros(n,1) ;
pcolor(lon,lat,RF') ; shading interp ;
hold on
for i = 1:n
x = S(i).X ; y = S(i).Y ;
plot(x,y,'k')
% rfi = interp2(lon,lat,RF',x,y) ;
end
