How do I plot a US state using the mapping toolbox?

I need to plot California and then have to label points on the map based on latitude and longitude coordinates.

I got mapping toolbox for the first time and am confused about how to do this.

I checked the general help section and it didn't help much.

So I was able to plot California but still don't know how to plot points.

To plot a US State and points on it, you could something as shown below:

%Read vector features and attributes from shapefile
cali = shaperead('usastatehi', 'UseGeoCoords', true,'Selector',{@(name) strcmpi(name,'California'), 'Name'});

axesm mercator; %Define Map axes
geoshow(cali); %Display map
plotm(lat,lon,'Color','r','Marker','.','MarkerSize',50); %plot point at [lat,lon] location

You have to assign appropriate values to the lat and lon variables. The above code plots the California state with a point at lat = 39 and lon = -123.6234. Similarly you can use the other plotting functions available here.

Hi, using this code how can I add the longitude and latitude on x and y axis in the map?
