Hello, i am still new to Matlab and coding. Currently im stuck in how to combine these array from different cells into one cell.
Each cell array has different number of rows!
Can I combine alltogether into one cell. If yes, is there any efficient way to do this?
Thank you in Advance.

This is called concatenation. See the documentation of the function CAT. Matlab allows you to concatenate a bunch of column vectors into a single column (or row vectors into a single row), even if they have different lengths.
v1 = [1 ; 2 ; 3] ;
v2 = [5 ; 6] ;
Y = cat(1, v1, v2) % a single column vector
However, concatenating column vectors if different lengths into multiple columns is not allowed, because the resulting array is not rectangular. Somehow you need to fill up the empty spaces. This is exactly what my function PADCAT does:
% cat(2,v1,v2) % error!
M = padcat(v1, v2)
When your vectors are stored in a cell array, as in your question, using comma-separated list expansion makes it quite easy.
C = { [1 ; 2 ; 3], 4, [5 ; 6 ; 7 ; 8 ; 9], [10 ; 11] }
M = padcat(C{:})
PADCAT can be downloaded from the File Exchange: https://uk.mathworks.com/matlabcentral/fileexchange/22909-padcat
