MATLAB: Extract elements from a cell array

Question

Hello,

Please help me with the following:

Consider a 3×1 cell array where its cells contain matrices as shown below:

C{1,1}= 206×89

C{2,1}= 78×89

C{3,1}= 108×89

How can I extract the first 20 elements of each matrix and stored them in a new cell?

The final matrices will be

206×20

78×20

108×20

Thank you very much.

Pavlos
