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

Accepted answer

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

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!

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.

between every set of data there is a cell row free.
