The issue you are encountering with the random ordering of row indices i when using [i,j] = find(G==max(G,[],2) is due to how "find" function works.
The "find" function scans the matrix in column by coumn and returns indices in the order it encounters them.
To preserve the sequential order of the row values from 1 to 9, you can use a different approach. Instead of using find, you can directly work with the logical matrix M to obtain the row and column indices of the max values, ensuring they are in the order of the rows.
Here's how you can modify your approach:
- First, figure out which column has the highest value for each row.
- Use the "sub2ind" function to turn those row and column numbers into positions in the matrix.
- Then, get the values from those positions.
G = [2 1 3
4 8 12
3 4 2
2 1 3
4 8 12
3 4 2
2 1 3
4 8 12
3 4 2];
S = repmat((200:202), [9,1]);
[~, j] = max(G, [], 2);
% here j is column wise index
% i is row index
i = (1:size(G,1))';
% calculate the linear indices
linearIndices = sub2ind(size(S), i, j);
% find the value based on linear Indices
S(linearIndices)
Hope it helps!
