MATLAB: Remove lines from logical matrix if values in 3 or more rows are equal to 1.

logicalsmatrix

If I have the matrix which has logical values

a = [0 0 0 0 0; 0 1 1 0 0; 1 1 0 1 1];

Then I would like to remove the last line as three or more values are 1 in them.

a = [0 0 0 0 0; 0 1 1 0 0; 1 1 0 1 1];
a(sum(a,2)>=3,:)=[]

MATLAB: Generate increasing exponential series for 10 numbers with sum equal 1.

v = rand(1, 10);
v = sort(v) / sum(v)

would be one way to generate a monotonically increasing vector of 10 numbers.

MATLAB: How to place a cell array in another cell array using ‘find’

If I understood correctly:

Ax = randi([0 1], 4, 960);  %Demo data. No way I'm reformating your example to make it valid matlab syntax. 
[row, col] = find(A);
blockidx = discretize(col, 1:60:size(A, 2));
Bx = accumarray([row, blockidx], col, [], @(c) {sort(c).'})

Note: I'm not working on the whole cell array here, just one of these 4x960 matrix as I've not understood what that had to do with the question. Possibly, you just want to above in a loop (or cellfun) operating over each element of the cell array.
