Indexing vectors in a cell matrix with for loops?

Hello,

I have a 1x8 cell matrix. Each cell contains a 30x500 matrix. I need to combine the 3 first row vectors in each cell to form a new matrix. The new matrix needs to have 8 columns, each column representing the original cell. That being said, the 3 original row vectors have to be combined in one column vector. My final matrix will be 1500x8.

Basically, I have no idea how to index vectors from each cell to form a new matrix.

Thank you in advance.

if true
  % You can either use this
A{1}(1:3,:) %to extract the first 3 rows of the 1st matrix, and the same for all. 

   % Or convet the cell to mat, then you know the rest
B = reshape(cell2mat(A),30,1500,8);

newmat=zeros(1500,8)
for k=1:8
  t=yourCell{k}(1:3,:);
  t=t';
  newmat(:,k)=t(:);
end
