convert matrix of cells into matrix of vectors

hello,please i have matrix of cells contain 32*32 cells,each cell have 8*8 double values,i want to covert this matrix into matrix of vectors such as the size of the resulting matrix is 1024*64,i trying in this code but the size views as 32*64,where A1 is a cells matrix

    
    for i=1:size(A1,2)
        for j=1:size(A1,2)
        A2(j,:)=reshape(cell2mat(A1(i,j)),1,[])
        end
 end

There are different method to concatenate the matrices to the wanted output. One is:

X = cat(1, A1{:});
X = reshape(X, 1024, 64);

Joining along the 2nd or 3r dimension is possible also: cat(2, ... or cat(3, ... .

In your codeyou overwrite A(j, :) repeatedly in the inner loop.
