How do I split a string of numbers in n+1th successive intervals and put them in a array or matrix.

I need to split a string of numbers, for example-

123456123456123456123.....

into separate elements in the form

12345612

23456123

34561234

45612345

56123456

61234561

.....

and so on.....where the next element starts from the n+1th number in the string and size remains same.

Another option is to use a loop:

n = '123456123456123456123';                            % Convert To Character Array
len = 8;                                                % Length Of Segments
for k = 1:numel(n)-len+1
    s(k,:) = n(k:k+len-1);                              % Character Array
    sn(k,:) = str2double(s(k,:));                       % Numeric Array
end

Experiment to get the result you want.
