I have to create a 2D matrix, where the row number is unknown. I will have to find the row number.
Say, for i=1:5
for j=1:3
I want to create a 2D matrix with 2 columns, where the entries will be like [i j]
How should I write the code?

Your question is not at all clear. What exactly are you looking for? Can you give a better example?

If you know column numbers and don;t know row number; you can initialize as below;
iwant = zeros([],col) ;
If you know row numbers and dont know column number; you can initialize as below;
iwant = zeros(row,[] ;
But, it seems in your case:
iwant = zeros(5,3) ;
for i=1:5
for j=1:3
iwant(i,j) = rand ;
end
end
