It may still balk, because the cell contents are numeric. In that case, you could use num2str or sprintf to convert the numeric arrays. You can convert uint8 and uint16 data to double precision using the MATLAB function, double. However, converting between storage classes changes the way MATLAB and the toolbox interpret the image data. If you want the resulting array to be interpreted properly as image data, you need to rescale or offset the data when you convert it. This process takes on average: 1.2561 seconds, then, adding this to save process is 8.3351 + 1.2561 = 9.6 seconds which sounds better than the 2.6 minutes using # ndarray --> list --> single. Then, for now, this is my solution: save to disk, store the path as a variable into Matlab's workspace, and then load it from the disk. For than the tensor object need to be converted to numpy array.
