how to concatenate the cell data into a single matrix?

All the data samples are of same length. i need to create a matrix containing all this data. there are 327 cells like this in continuation.

One of the way is to use cell2mat

What size of output are you looking for? (3*328) by 256? Or 3 x (256*328) ? Or 3 x 256 x 328 ? Or a single vector?

I need a single matrix with all data of cells i.e 3*256 arranged as coulmn wise i.e (256*3) for all 327 cells. so that finally i will end up with the dimension of (256*3)*327

Single_Matrix = cell2mat(cellfun(@(C) C(:), YourCell, 'uniform', 0));

However, I am concerned about whether this will work. You said twice that you have 327 cells, but your header shows that you have a 1 x 328 cell array. Is one of the cells empty and that is why you say 327 ? If so then what do you want done about the empty cell?

my 328th cell is empty. and i have nothing to do with it.

i am getting this errors

Error using cat

Dimensions of arrays being concatenated are not consistent.

Error in cell2mat (line 75)

m{n} = cat(2,c{n,:});

Error in shresth_p (line 50)

Single_Matrix = cell2mat(cellfun(@(C) C(:), Interpolated_data, 'uniform', 0));

[Walter Roberson]

 Single_Matrix = cell2mat(cellfun(@(C) C(:), Interpolated_data(1:327), 'uniform', 0));

THANK YOU SO MUCH WALTER SIR!!
