Combining Cells into a single cell

How can I combine multiple cells in to a single cell
there are 6 cells, each m x n format (n is 17 in all)
I want a new cell created that just adds up below
so for example Cell1 is 50x17 Cell2 is 30x17 Cell3 is 20x17
new cell should then be : AllCell is 100x17
I thought of:
Allcell=cell(Cell1+Cell2+Cell3,17);
but what then

You should find your way from there on, and combine content of cell arrays.
It slightly confusing: Do you want AllCell to be a scalar cell, which contains a 100x17 matrix?
I found a way but i think it should be easier.
raw is from xlsread, a cell.
A=length(raw1);
B=length(raw2);
C=length(raw3);
D=length(raw4);
E=length(raw5);
F=length(raw6);
lengthcell=A+B+C+D+E+F;
All=cell(lengthcell+5,17);
All(1:A, 1:17)=raw1;
All(A+2:A+B+1, 1:17)=raw2;
All(A+B+3:A+B+2+C, 1:17)=raw3;
All(A+B+C+4:A+B+C+D+3, 1:17)=raw4;
All(A+B+C+D+5:A+B+C+D+E+4, 1:17)=raw5;
All(A+B+C+D+E+6:A+B+C+D+E+F+5, 1:17)=raw6;
between every set of data there is a cell row free.
AllCell = [Cell1; Cell2; Cell3];

use the standard concatenation operator [ ]
AllCell = [Cell1; Cell2; Cell3; Cell4; Cell5; Cell6];

hmm, i tried this but with , instead of ; inbetween the Cells.
Thank you
Thanks a lot dear Thorsten. It reclaim me

If your cells are not called "Cell1", "Cell2", ... but you use an index as index (as suggested repeatedly and consequently in this forum), the concatenation is even easier:
C{1} = rand(50, 17);
C{2} = rand(10, 17);
C{3} = rand(40, 17);
C{4} = rand(30, 17);
C{5} = rand(20, 17);
AllC = {cat(1, C{:})};

Why even mess with cells, if it's just a simple numerical matrix at that point? Just simplify it
theBigArray = cat(1, C{:}); % A matrix, not a cell - simpler, yay!
But the OP asked for the output to be a cell explicitly: "Allcell=cell(...".
Yeah, I know. But she's a beginner and beginners often think they want something when some other way is better, simpler, and easier. For example to get the 5th row, 16th column you could simply and naturally do theBigArray(5, 16). OR do something more complicated like AllCell(1){5, 16} or maybe it's just AllCell{5, 16} or something like that - I always have to play around with braces and parentheses til I get it right, that's why I avoid cell arrays if at all possible.
thanks simon, very usefull
thank you so much mr.simon. this is working very well.
