I would like to make contours of elevations. My text file which contain lat, lon and elevation data set. I want to genterate contours of this elevation data set.on this help vedio and documentations i able to prepare this code as starting
a=load('2002dec.txt');
>> x=a(:,1);
y=a(:,2);
>> z=a(:,3);
>> [x,y]=meshgrid(60:0.5:78,21:0.5:38);
>> contour(x,y,z)
But getting error.
I also want to set a shape file as back ground of these contours.Any guide line will be highly appriciable.
My text file data and shape file has been attached with this post

shapefile = 'PAK_adm1.shp' ;
S = shaperead(shapefile) ;
data = importdata('2002dec.txt') ;
x = data(:,1) ; x = unique(x) ;
y = data(:,2) ; y = unique(y) ;
z = data(:,3) ;
[X,Y] = meshgrid(x,y) ;
Z = reshape(z,size(X)) ;
pcolor(Y,X,Z) ; shading interp ;
hold on
for i = 1:length(S)
plot(S(i).X,S(i).Y,'k') ;
