How can I export Matrices in a Cell data?

I have a cell array which contains matrix data that I want to export:

 x    x    x    x    x    ...
 x    x    x    x    x    ...

Each 'x' is a different matrix written as, say, [1 2 3; 4 5 6; 7 8 9]

I want to export this cell array (with dimensions 2 by n), and I want each x matrix to be exported in standard matrix notation, not semicolon notation:

       [1 2 3]
   x = [4 5 6]
       [7 8 9]

Therefore, when I export the data I want to have:

 [1 2 3]    [5 2 3] 
 [4 5 6]    [1 2 2]    ...
 [7 8 9]    [7 8 9]

 [5 2 3]    [4 5 6]   
 [3 5 6]    [7 2 9]    ...
 [7 1 9]    [5 2 3]

How can I do this? Thank you!

What do you mean, precisely, by "export" here???

I want to print this data as tidy as possible.

Problem with the cell data is, when I print, it is hard on the eye because of the usage of semi-colons for each new row.

I want the data to be shown as something similar to the provided example.

Thank you.

Are all of the cells the same size? Are they integer data or floating point?

Since you didn't mention signs, perhaps the following suffices:

    A=randi([1 10],randi([3 10],1,1),randi([3 10],1,1))
    [sz1A sz2A]=size(A)
    B=[repmat('[',sz1A,1) int2str(A) repmat(']',sz1A,1)]

create a function with these lines, for instance fun1

    function Y=fun1(X)
    X2=cell2mat(X);
      [sz1X sz2X]=size(X2);
      Y=[repmat('[',sz1X,1) int2str(X2) repmat(']',sz1X,1)];
    end

and repeat for each element of the big matrix

a simple test, to generate the big matrix, just one dimension:

   % generate BigMatrix
    Cell_nulls={};
    for k=1:1:randi(10,1,1) 
       Cell_nulls=[Cell_nulls randi([1 10],randi([3 10],1,1),randi([3 10],1,1))]; 
    end

I considered cellfun, but you may want to write it all in a text file, because you mention you want to print it anyway.
