using mat2cell we can convert a big array in different cells but all are stored in a single variable as double matrices so how can we assign them to seperate variables......ie., we split A=140x13 matrix in to 100x13 and 40x13 with A0=mat2cell(A,[100,40]) command it will be stored as [100x13 double] [ 40x13 double] cells in the same variable ,,,so after splitting how can we pin 100x13 and 40x13 to two different variables

First read this: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

Then try this:

A = randi(9, [140, 13]);
A0=mat2cell(A,[100,40]) 
topRows = A0{1};
bottomRows = A0{2};
% Or even better
topRows2 = A(1:100, :);
bottomRows2 = A(101:end,:);
