Converting a cell array into a matrix of stipulated number of columns and rows

Consider I have a cell array containing 4 cells

Each cell containd 'n' elements

Now I want to covert it into an array of size "n*4" where element of each row is take from elements of each cell

If it has tto be more clear for eg: ist row of the matrix contains 4 elements - each element is picked from 1st element of each cell.

I have used the model

for i = 1:numel(W{1})%w is the cell
wid(i,:)=double(cellfun(@(v) v(i),W));
end

But it is taking more time in matlab.So, is there any best and simple solution for this problem which can be simulated in less time?

The code seems unnecessary. Please construct an example with n=2 and explain what is the input and desired output.

Have you tried with cell2mat?

Answer 1

[Andrei Bobrov]

Let C - your cell array.

if cells sizes are the same:

out = reshape(cat(2,C{:}),[],4); 

if not the same:

out = cell2mat(cellfun(@(x)x(:),C,'un',0));

Answer 2

wid = [W{1}(:) W{2}(:) W{3}(:) W{4}(:)];
