MATLAB: How to get the values of a matrix using movsum to add 90 consectuive cells in the matrix

MATLABmovsum

ex. I have 0 and 1 within a matrix, I want to see if there are 90 consecitives 1's within the matrix and what is the freqency of it is

Additional if cells 2 to 92 had 90 consecutive ones, i'd like it to reflect 90 but if it was 30 consecutive ones in a 90 cell range then i'd like the value to reflect 30

This task will be trivial if you use the RunLength utility from the File Exchange.

MATLAB: How to get the maximum of repetitive elements in certain portions of a matrix

The only way I can see to do this is with a loop that selects and analyses each 10-row segment.

This works:

A = [2 20;
    2 30;
    2 40;
    7 100;
    7 110;
    7 120;
    7 130;
    7 140;
    15 240;
    15 260
    4 20;
    4 30;
    4 40;
    10 100;
    10 110;
    10 120;
    16 130;
    16 140;
    25 240;
    25 260    
    4 20;
    4 30;
    4 40;
    10 100;
    10 110;
    10 120;
    16 130;
    16 140;
    25 240;
    25 260];
for k1 = 1:10:size(A,1)
    T = A(k1:k1+9,:);
    [uv,~,idx] = unique(T(:,1));
    B{ceil(k1/10)} = [uv accumarray(idx,T(:,2),[],@max)];   % Output Cell Array               
end

It seems to do what you want.

MATLAB: Detecting length and number of occurrences in a logical array

Download Jan's RunLength utility from the File Exchange. It will do exactly what you want.

array1 = [0 0 0 0 0 1 1 1 1 0 0 1 1 0 0 0 0 1 1 1 1 1 1 0 0 0 1];
[b n] = RunLength(array1);
array2 = n(b==1)
array2 =
     4     2     6     1
