.mat file to 3d array

I have a mat file called testdata3D.mat. I have to create a 3D array with the two pages and name it test_results.

 I loaded the page but I'm having a hard time putting it into a single array with two pages. I can do two separate arrays but not sure how to do a single array with two pages. Above is an image of what I have so far. Any help is highly appreciated.

Please post code and examples directly as text, because it is much easier to play with using copy&paste.

The loaded data is one string. Therefore I guess, that you have stored the .mat file in ASCII mode. You can try to read it in ASCII mode also:

data = load('-ASCII', 'testData3D.mat')

But it would be more efficient and powerful to store the data in the binary format.
