Matrix to array

I have a cell array of 192 X 64.Now I need to convert
each of the individual cells back into matrix(cell2mat), then
populate a row of a new matrix with the contents of the cell.

Basically I have B = 192 * 64 cell.
each is of the form B(1,1)=2x2 double.
converting to matrix, B = cell2mat(B(1,1))
Now I need to put this into New(1,1:4)=[B(1,1) B(1,2) B(2,1) B(2,2)].


The question I have is whether this can be done in a easier way since
it is'nt always 192*64, I have to go through every single cell, and
it is'nt always 2x2.

Reshape & Transpose (or .') are your friends ...

% create example data:
for i=1:10,
B{i} = repmat(i,2,2) ;
end
% NB All elements of B have equal elements
NewB = reshape(cell2mat(B),numel(B{1}),[]) .' ;

There surely must be a more elegant and efficient way to do it, but
here's a start:

%%%%%%%%%%%%
newB = reshape(B', 1, []);

for i = 1:length(newB)
New(i, :) = reshape(newB{i}', 1, []);
end
%%%%%%%%%%%%

This is if you want to go across the rows first and down the columns
of B. If you want to go down the columns first, then

newB = {B{:}};

Hope this works.

Jos,
Very clever. Let me add another thing to your code. If I understand
the OP, she wants to display rows first:

newB = reshape(B', 1, []);
New =  reshape(cell2mat(newB')',numel(B{1}),[])
';

Jiro,Jos:

Thank you! You saved me a lot of time and more importantly I learnt
something.
