MATLAB: How to plot contourf using following information

contourfMATLAB

I am having data as follows:

lon 256*1double

lat 128*1double

time 3654*1double

pr 256*128*3654double

I am using contourf(lon,lat,pr(:,:,:)) or contourf(lon,lat,pr(:,:,:)') but there is error of dimension

pr is a 3D matrix, you cannot use contourf on a 3D matrix. You need to draw layer by layer.

[m,n,p] = size(pr) ; 
for i = 1:p
    contourf(lon,lat,pr(:,:,i)) ; % if throws error, trispose pr
    drawnow
end

Also have a look on slice.

Are you looking for this?

M = 288 ; N = 180 ;
long=linspace(0,360,M);
lat=linspace(0,180,N);
[Long,Lat] = meshgrid(long,lat) ;

You cannot save [long(i) lat(j)] into res(i,j). res(i,j) needs a single number and [long(i) lat(j)] are two numbers. Else there should be some other relation between long and lat.

Let lon, lat, P be your matrices of size 470*160*140.

[m,n,p] = size(P) ;
for i = 1:p
    pcolor(lon(:,:,i),lat(:,:,i),P(:,:,i)) ; 
    shading interp 
    colorbar
    drawnow 
end

You can also use surf, contour, countourf.
