MATLAB: Generating Geographical matrix using Loop

for loop

I am trying to generate a 2D matrix for the geographical Longitude and Latitude, for the ranges below:
Φ = [0,Δφ,2Δφ, …, 179Δφ] Θ = [0,Δθ,2Δθ, …, 287Δθ] . I tried this
long=linspace(0,360,288); lat=linspace(0,180,180); res=zeros(288,180); for i=0:1.25:length(long) for lat=0:1:length(long) res(long,lat)=[long lat]; end end but I got this error
Subscript indices must either be real positive integers or logicals.
Error in odayalbedo (line 12) res(long,lat)=[long lat];
Any suggestions??? Thanks in advance

Best Answer

Are you looking for this?
M = 288 ; N = 180 ;
long=linspace(0,360,M);
lat=linspace(0,180,N);
[Long,Lat] = meshgrid(long,lat) ;
You cannot save [long(i) lat(j)] into res(i,j). res(i,j) needs a single number and [long(i) lat(j)] are two numbers. Else there should be some other relation between long and lat.
