how to store cells values of multiple images into a single file ?.

4 views (last 30 days)
I stored the 10 strongest points of Surf features into cells i.e.every cell contains 10 points of surf features strongest points and i have 40 images so total 40 cells contains 400 points, what i want to do is to get all the points for all the images (400 points for 10 images) into a single file in rows to further label it for classification. any help will be appreciated..thanks
here is the description link where what i did for storing the values for all 40 images into cells.

What do you mean with "single file in rows"? Do you mean you want an array of 400 x 1?

Load all of the data into a cell array, one entry per file Then
data_array = cell2mat( cellfun(@(C) reshape(C,1,[]), TheCellArray(:), 'uniform', 0) );
Now the entire content of each file will be put into a single row, and the rows (files) will be put together into a 2D matrix.
This code as-written will fail if the files are not all the same size. If that is a problem then you would need to define how you want to store the data in that situation.
