loc = [i j 1 1];
count = [1 1 inf inf];
varname = 'temp';
tempdata = ncread( ncfile, varname, loc, count);
However I do not know if ncread will be able tell the remote side what it wants to read, or if it has to read the whole thing and then select from it.
Also it would not surprise me if you need j i instead of i j

That worked great thanks so much!
I need to create a loop whereby I add one day onto the initial file (01/11/21) - there are files on the server for each day
This is so that i can extract the same data for each day over the course of a month (Nov 2021) - into a matrix
Do you have any ideas on how to go about this? I am unsure how to do this from a server file

ncfile = sprintf('https://dapds00.nci.org.au/thredds/dodsC/fx3/gbr1_bgc_GBR1_H2p0_B3p2_Cfur_Dnrt/gbr1_bgc_simple_2021-11-%02d.nc', DAYNUMBER);
