So, it seems you can set the position of each subplot, BUT (big BUT here), you have to pre-create all the subplots first and THEN set the position. Otherwise, if the position of one subplot overlaps the position of any previous subplot, then it wipes it out.
Note that position is [left bottom width height]
figure;
set(gcf,'position',[103 438 2354 907],'PaperPositionMode','auto','BackingStore','off','PaperOrientation','landscape');
cnt=0;
nr=3;
nc=4;
mn=nanmin(data_moclim.(varnames{vv})(:));
mx=nanmax(data_moclim.(varnames{vv})(:));
for jj=1:12
cnt=cnt+1;
s(jj)=subplot(nr,nc,cnt);
end
cnt=0;
for jj=1:12
cnt=cnt+1;
subplot(s(jj))
if rem(jj,nc)==0
s(jj).Position=[1-(1/nc) 1-(ceil(jj/nc)/nr) 1/nc 1/nr];
else
s(jj).Position=[(rem(jj,nc)/nc)-(1/nc) 1-(ceil(jj/nc)/nr) 1/nc 1/nr];
end
ax=worldmap('World');
setm(ax,'Origin',[0 -160 0]);
colormap(jet(250));
caxis([mn mx]);
pcolorm(data.lat,data.lon,data_moclim.(varnames{vv})(:,:,jj));
geoshow(land, 'Facecolor',[0.5 0.5 0.5]);
set(gca,'fontsize',18,'fontweight','bold');
drawnow;
end
