Hello,

Please help me with the following:

Consider a 3x1 cell matrix called C, where

each cell element contains matrices with different number of rows, for example:

C{1,1}=a 100x10 matrix

C{2,1}=a 20x10 matrix

C{3,1}=a 30x10 matrix

How can I extract separate different sub-matrices (maybe with a for loop)?

For example,

for i=1:3

submatrix(i)=mat2cell(C(i,1));

end

I need 3 different sub-matrices.

Thank you very much.

Pavlos

Hint:

    >> C{1,1} = rand(100,10);
    >> sub = C{1,1}( [2:4], [1:6] )
    sub =
