Good morning everyone, I ran a simulation with SWAN (Simulating WAve Nearshore) and I am trying to plot several variables on a meshgrid.
I have two matrices: a 72x77 matrix that represents the x-coordinates of the points of the grid and a 72x77 matrix that represents the y-coordinates of the points of the grid. ( These two matrices have Na values in some locations because there are some land obstacles in the domain) With these two matrices I would like to plot the meshgrid and then plot any variable above it ( also 72x77 matrix). For example, the first variable that I would like to show is the water depth, since I want to obtain a bathymetry plot.
Thank you a lot for your help in advance.

Ran in:
%% Your example
data = magic(4);
data(1,2) = nan;
x = [1,2,3,4];
lat = repmat(x,4,1);
lon = lat';
surf(lon,lat,data);view(2);
