how do I create a loop for to extract doubles variables from a cell array?

I have a cell array (10x1) that contain 10 [300x2000] double variables. I need to extract each double varables contained in each cell, rename it with the name "raster_data" and save each of them in a separate file.mat. This for loop allows me to generate a file.mat, but for achieve my final goal I should insert in each file.mat the variable "raster_data" .

Do you have any idea how I can complete the loop for?

for greater clarity I enclose also the data on which I have worked

thanks for any suggestion

for k = 1 : length(filename)  
  baseFileName = sprintf('%s.mat', filename{k});
  fullMatFileName = fullfile(folder, baseFileName);
  save(fullMatFileName, 'raster_labels');  
end

Where raster_data is your cell array:

for k = 1:numel(filenames)
    raster_labels = raster_data{k};
    ... the rest of your code
end
