MATLAB: Anomaly with comments and rating in one file in File Exchange.

'anomaly' 'comments' 'file exchange'

https://www.mathworks.com/matlabcentral/fileexchange/85900-seawater-density-from-salinity-temperature-and-pressure

I posted this:

clc
lon=30;
conduc=linspace(0,2000,lon);
sali=zeros(1,lon);
for k=1:lon
    sali(k)=conduc2sali(30,0,conduc(k));
end
figure(1)
close(1)
figure(1)
plot(sali,conduc)
xlabel('salinity')
ylabel('conductivity')
% Can conductivity drop this quickly with salinity?

All the comments and the ratings disappeared for that file almost suddenly and mysteriously. Can someone explain what happened?

MATLAB: How to plot multiple 3d plots using the ‘geoplot3’ and ‘geoglobe’ functions

There are two things to keep in mind while using the 'geoglobe' function to plot multiple plots:

1. Firstly, the 'geoglobe' function has a default property of deleting existing plots and reset globe properties, except Position and Units, to their default values before displaying the new plot. In order to allow multiple plots to be plotted on the globe the user needs to specify the 'NextPlot' name-value pair argument as 'add' as shown below in the example:

uif = uifigure;
g = geoglobe(uif,'NextPlot','add');

Additionally, please refer to the following documentation regarding the NextPlot property:

https://www.mathworks.com/help/map/ref/globe.graphics.geographicglobe.html#mw_6c760b8f-7d02-4f56-95f1-85a0ec557e20

2. Secondly, only certain 'hold' syntaxes are supported by the 'geoglobe' function as shown below:

hold(g) %toggles the state between off and on
hold(g,'on') % retains plot so that new plots can be added to the same plot
hold(g,'off') % releases the current plot

Please refer to this documentation link which describes the supported 'hold' syntax:

https://www.mathworks.com/help/map/ref/globe.graphics.geographicglobe.html#mw_6ed71245-e876-4a96-9bb1-eb2162df345d

Additionally, please refer to this sample MATLAB code that will demonstrate how to plot multiple line plots over a local region using the 'geoplot3' function:

trk = gpxread('sample_mixed','FeatureType','track');
lat = trk.Latitude;
lon = trk.Longitude;
h = trk.Elevation;
lat1 = 0.98*(trk.Latitude);
lon1 = 0.98*(trk.Longitude);
h1 = 0.98*(trk.Elevation);
uif = uifigure;
g = geoglobe(uif,'NextPlot','add');
geoplot3(g,lat,lon,h,'c')
hold(g,'on')
mskip = 1:25:length(lat1);
geoplot3(g,lat1,lon1,h1,'ro','MarkerIndices',mskip)

Resulting figure:

MATLAB: Three dimensional plot using 4 variables

For the contour plot, you can use

contour(lon,lat,salinity')

If you want the filled contour plot, then you can use

contourf(lon,lat,salinity')

If you want labels on the contour plot, then you can use clabel
