MATLAB: Can Anyone explain this code to me ?

contourflatlonmeshgridplotxyz

[lon0,lat0]=meshgrid(65:0.05:80,68:-0.05:10);
%%%%====================================================
% pcolor(lon0,lat0,Rtarea21);
lon1=lon0(500:1:800,20:1:60); lat1=lat0(500:1:800,20:1:60);
R=Rtarea10(500:1:800,20:1:60);
K=Rtarea10(945:1:955,245:1:255);
K1=mean(K);
K2=mean(K,2);
TepR=mean(K1);
% TepT=Rtarea10(949,248)
TepT=Rtarea10(944,250);
contourf(lon1,lat1,R);

Best Answer

The code creates a grid of data spaced every 0.05 apart from 65 to 80 and 68 to 10, and extracts part of it. It also extracts part of Rtarea10 matching the same locations. It uses the extracted grid as the x and y coordinates to do a contour plot on the extracted Rtarea10
