split 3 dimesnsional array into equal blocks along the first 2 dimensions

images is a cell array of 12 images. I want to split images into many rectangular blocks, with each of the 12 images stacked together. The following code achieves what I intend, but I hoping if someone could verify that this is the most efficient code that can be written. I am new to matlab and hence not ver confident.

 xParts = 5;   %divide rows into 5 parts.
 yParts = 5;   %divide columns into 5 parts.
 mdImages = cat(3, images{:});   %convert cell array to 3 dimensional matrix

 %get vector for: how to split the rows.
 xSplit = repmat(floor(size(mdImages,1)/xParts), [1 xParts]);     
 xSplit(end) = xSplit(end) + mod(size(mdImages,1), xParts);

 %get vector for: how to split the columns.
 ySplit = repmat(floor(size(mdImages,2)/yParts), [1 yParts]);
 ySplit(end) = ySplit(end) + mod(size(mdImages,2), yParts);

 imgCells = mat2cell(mdImages, xSplit, ySplit, [size(mdImages, 3)]);

 %convert each cell from 3 dimensional matrix to 2 dimensional.
 sequences = cellfun(@(x) reshape(x, [], size(x, 3)), imgCells, 'UniformOutput', false);
