Repeating the same statement using loop

Question

This is the same statement for 3 times. how to do this with loop. Here, the matrix G1 dimension is 3*10. so in each part i am taking different column.

G2 = f_range_m(1:8:length(timeline_ms),:); %%%% measured range
G1 = OrgiRange(1:8:end,:);

M1 = G1(:,1);
dist11 = abs(bsxfun( @minus,G2,M1));
[~,col1] = min(dist11,[],2);
Result_1 = diag(G2(:,col1));


M2 = G1(:, 2);
dist22 = abs(bsxfun(@minus,G2, M2));
[~,col2] = min(dist22,[],2);
Result_2 = diag(G2(:,col2));

M3 = G1(:, 3);
dist33 = abs(bsxfun(@minus,G2, M3));
[~,col3] = min(dist33,[],2);
Result_3 = diag(G2(:,col3));

I am trying this way. However not getting desired output. Result dimension should be 13*3.

obj = 3;
for ix = 1:obj
    M = G1(:,ix);
    dist = abs(bsxfun(@minus,G2,M));
    [~,col] = min (dist,[],2);
    Result = diag(G2(:,col));
end

The problem with your code are the variable names you are using. You have to use arrays or cell arrays instead of variable names like M1 M2 M3. If you rewrite the code this way, going to a loop is straight forward. You just replace the M{1} with a M{ix} where ix is your loop iterator. Alternatively if you don't need M after the calculation just use M and overwrite it in each iteration. Do the same for dist, col and Result and you got a solution. — Daniel

With your updated code you nearly solved it. Everything which remains is writing to the columns of Result instead of overwriting it in each iteration.

obj = 3;
Result=nan(size(G1,1),obj);
for ix = 1:obj
    M = G1(:,ix);
    dist = abs(bsxfun(@minus,G2,M));
    [~,col] = min (dist,[],2);
    Result(:,ix) = diag(G2(:,col));
end
