s = load('yourFile.mat');
image3d = s.image3d; % Whatever it's called.
[rows, columns, slices] = size(image3d)
outputFolder = pwd; % Wherever you want.
for slice = 1 : slices
thisSlice = image3d(:, :, slice);
baseFileName = sprintf('Slice %d.tif', slice);
fullFileName = fullfile(outputFolder, baseFileName);
imwrite(thisSlice, fullFileName);
end

inputFolder = pwd; % Wherever you want.
outputFolder = pwd; % Wherever you want.
for slice = 1 : slices
% Read in image from mat file.
baseFileName = sprintf('Slice %d.mat', slice);
fullFileName = fullfile(inputFolder, baseFileName);
if ~isfile(fullFileName)
continue; % Skip it if it does not exist.
end
fprintf('Reading %s.\n', fullFileName)
s = load(fullFileName)
thisSlice = s.theImage; % or whatever it's called.
% Write out as a TIFF format image file.
baseFileName = sprintf('Slice %d.tif', slice);
fullFileName = fullfile(outputFolder, baseFileName);
fprintf('Writing %s.\n', fullFileName)
imwrite(thisSlice, fullFileName);
end
