Assignment error in double loops

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 must get 180X288 matrix pls help

[KSSV]

What is the relation between long and lat to get required matrix?

[Oday Shahadh]

I just need to arrange:

long=linspace(0,360,288); lat=linspace(0,180,180);

in a 180X288 matrix to

[KSSV]

[X,Y] = meshgrid(long,lat)
