Hello Is there some method to play a lat/long map from a grd file (with x,y,z information)? It would be a bathymetric map. I have a grd referent to the bathy and onother one of the slope. I use GMT package commonly. But it is separated of MATLAB. Then, I would like to do some automatization to plot on MATLAB after some data process done on my code. I am grateful for any example.

Hi, ok. I was trying this command:
[X_bathy,Y_bathy, Z_bathy]=grdread2('bathy.grd');
[xLon, yLat] = meshgrid(X_bathy,Y_bathy);
figure()
Z_bathy_elements=numel(Z_bathy);
colororder(parula(Z_bathy_elements));
surf(xLon, yLat, Z_bathy);
view(2);
colormap parula
but all the figure was black color without shows the bathy variation. Do you know why?
