I have saved 100 iterations data in a cell using command

% here x is a matrix that contains 7 variables 
% so M_n has a dimension 1xi where i=100 in this case; 
% in each i has dimension 7X1 cell ; 
%in each iteration,  each state vector in x share same no of enteries but the size of each state changes with iteration..the no is not known a priori ..
%for example at i=1, each state in x has total 8000 enteries whereas at i=2, each state in x has 45 enteries...and so on..how to access this data ...%

% similarly time has  1xi dimension..each i has 1x1 cell..in each cell,
% different no of enteries are there ..but no of enteries are equal to no
% of enteries in each state 
t_new(i)=mat2cell( t, [size(t,1)], ones( 1, size(t,2) ) );
M_n{i} = mat2cell( x, [size(x,1)], ones( 1, size(x,2) ) );
