I tried this
long=linspace(0,360,288);
lat=linspace(0,180,180);
res=zeros(length(lat),long(lat));
for i=1:length(long)
for j=1:180
res=[long(i) lat(j)];
end
end
and got this error
Subscript indices must either be real positive integers or logicals.

Change
res=zeros(length(lat),long(lat));
to
res=zeros(length(lat),length(lat));

Thanks but it does not save the loop in preallocation matrix, Do I have to use: res(i,j)=[long(i) lat(j)]; instead?

I just need to arrange:
long=linspace(0,360,288); lat=linspace(0,180,180);
in a 180X288 matrix to
