rearranging the data in separate columns when difference of 10 is found in vectors

I have data like: 1,2,3,4,5,7,8,11,13,14,15,17,18,19,21,23,24...34..,

Here, I would like to divide this series into columns as soon as the difference of ten from the initial number is found in the vector. I.e: Column one will contain, 1,2,3,4,5,7,8,11 and Column 2 will 13,14,15,17,18,19,21,23, and third column the values from 24...34 and so forth.

The initial values changes relatively and starts at last break value. i.e. first relative value would be 1, second 13, third 24 and so on.

These can also be copied in independent matrices, say: A, B, C, D... and each contains vector whose first value and last value differ by 10. But, size of A,B,C,D... need not be identical.

Any hints or example code would be highly helpful.

Answer 1

[Andrew Newell]

You could do this using a cell array:

% preallocate array
n = ceil(max(x)/10);
y = cell(n,1);

% populate it
for ii=1:n
  y{ii} = x(x>10*(ii-1) & x<=10*ii+1);
end

See Cell arrays and Using logicals in array indexing.

A - your vector (issorted(A) == 1)

n = A;
out = [];
while ~isempty(n)
    k = (n - n(1)) <= 10;
    out = [out;{n(k)}];
    n = n(find(k,1,'last')+1:end);
end
