Hi,

I am trying to store the output of a for loop in a cell array -

x = [0,0,0,0,0,5,6,4,3,4,5,6,3,3,5,5,6,3,0,4,4,5,4,4,9,9,0,223,32,4,0,0,0,1];
A = x; 
B = zeros(size(x));
n = 1; 
B(n+1:end) = A(1:end-n);
branches = cell(zeros());
for i = 1:length(A)
    log = abs(A-B) > 5;
    no_branches = length(x(log));
end

Whenever the difference between elements in the vector is more than 5 I want to chop the vector and store that as Branch 1, and then continue in Branch 2 until the difference is again more than 5, and then move onto Branch 3, and so on and so forth...

Does anyone have any ideas on this please? I can only seem to get the number of times it happens rather than separate the vector when it does.

Cheers

What exactly is "the difference between elements"?

在 MATLAB Online 中打开

Maybe:

x      = [0,0,0,0,0,5,6,4,3,4,5,6,3,3,5,5,6,3,0,4,4,5,4,4,9,9,0,223,32,4,0,0,0,1];
Branch = cell(numel(x), 1);  % Pre-allocate!!!
ini    = 1;
iB     = 0;
for ix = 2:numel(x)
  if abs(x(ini) - x(ix)) > 5
    iB         = iB + 1;
    Branch{iB} = x(ini:ix - 1);
    ini        = ix;
  end
end
% Care about last chunk:
iB         = iB + 1;
Branch{iB} = x(ini:numel(x));
Branch     = Branch(1:iB);
