Wire the 3D array to it, and expand it to add another dimension so you can specify the number of rows and columns, and you'll get a 2D array. NumPy also provides a reshape function to resize an array. Cell arrays themselves must still be rectangular in any given two dimensions, and since each element is a cell, the array is filled with items that are all the same type. Say if your images are named as 'Image_1. For the other arrays B,C,D I would like to obtain 2D arrays Mb, Mc, Md that would correspond to the same indexes idx along the Z axis of B, C, D.
