In matlab, I am trying to extract netcdf data for a vector of latitude and longitudes to develop a time series. My code only produces a time series for an individual lat long value. Can someone please help me code a matlab program that will let me plot a vector of lat long values? My code is attached below, thank you.

lat=nc_varget('/Users/Ajanardhanan/Documents/MATLAB/Complete_TMAX_LatLong1.nc','latitude');

lon=nc_varget('/Users/Ajanardhanan/Documents/MATLAB/Complete_TMAX_LatLong1.nc','longitude');

t=nc_varget('/Users/Ajanardhanan/Documents/MATLAB/Complete_TMAX_LatLong1.nc','temperature');

time=nc_varget('/Users/Ajanardhanan/Documents/MATLAB/Complete_TMAX_LatLong1.nc','time');

a=find(lon==72.5);

b=find(lat==30.5);

r=t(:,b,a);

plot(time,r)
