How to find the number of continuous data set along each row in the matrix given below? Desired result given below.

V =[0 0 1 1 1 0 1 1;1 1 0 0 0 0 1 1;0 0 1 1 1 0 0 0;1 1 1 0 0 1 1 1;0 1 1 1 0 0 1 1;0 1 1 0 0 1 1 0;0 1 1 1 1 1 1 0]

desired_result=[2;2;1;2;2;2;1]

[Shantanu Dixit]

can you explain the question a bit more clearly and the rationale behind the desired result?

[Payel]

By continuous data I tried to mean consecutive non-zero values. In the first row there are 2 sets of continuous data; first set (1 1 1) and second set (1 1). In the third row there is only one such set i.e. (1 1 1). I want to calculate the number of sets of such continuous data along each row. Desired result variable shows the number of such sets along each row.

Exactly what is different in this question from the one where you got two answers already?

Hey @Payel

You can try something like this :

V = [0 0 0 0 0 0 0 0;
     1 1 0 0 0 0 1 1;
     0 0 1 1 1 0 0 0;
     1 1 1 0 0 1 1 1;
     0 1 1 1 0 0 1 1;
     0 1 1 1 1 1 1 0;
     0 1 1 1 1 1 1 0];

desired_result = zeros(size(V, 1), 1);

for i = 1:size(V, 1)
    counter = 0;
    for j = 1:size(V, 2)
        if (V(i, j) ~= 0) && (j == 1 || V(i, j - 1) == 0)
            counter = counter + 1;
        end
    end
    desired_result(i) = counter;
end
