How can I format a large cell of data into one big column underneath a (predeclared) title?

My goal is to generate some kind of 'tabular' representation of data and then output this filtered dataset to a new file. Something that looks like:

Foo Bar Fubar

0 0 0

1 100 50

................(54321 lines later)

.......................................

54321 0 1441

The only way I can obtain the data though is through a 1x1 struct containing 2 regions of 155x1 cell, 1 called titles, 1 called data.

So, what I do is...

titles = transpose(theStruct.theTitles(index));

*Index is the already known set of indexes I'm pulling Foo/Bar/Fubar titles from

my_storage = titles;                                 %foo, bar, fubar header titles
my_storage{2,1} = transpose(theStruct.theData{6,1}); %foo data
my_storage{2,2} = transpose(theStruct.theData{7,1}); %bar data
my_storage{2,3} = transpose(theStruct.theData{8,1}); %fubar data

What I end up getting though is just the cell arrays containing all doubles in 'theData{6,1}'/'theData{7,1}' in 'my_storage', so it looks like:

Foo Bar Fubar

54321x1 double 54321x1 double 54321x1 double

Foo, Bar, and Fubar are ALL cells as well too, which seems like it 'might' be problematic to write to files with.

I played around with 'my_storage(:,1)' (colon operator) to try to modify it to write its contents to all data underneath, but it didn't work based off what I tried.

How could I have the entire cell underneath Foo, Bar, and Fubar (the 54321x1 double cell) turned into just a large column of data? Is there a built-in, simple method that doesn't involve a raw for-loop?

Thanks!

Can you upload the struct?

Try this:

my_storage = titles;                                 %foo, bar, fubar header titles
my_storage_mat = [transpose(theStruct.theData{6,1}),...   % foo
    transpose(theStruct.theData{7,1}),...                 % bar
    transpose(theStruct.theData{8,1})];                   % fubar
my_storage_cell = mat2cell(my_storage_mat,ones(size(my_storage_mat,1),1),ones(size(my_storage_mat,2)),1);
my_storage = [titles;my_storage_cell];

You should get what you need, let me know if you have doubts.

Thank you, I seem to be getting a neater matrix, but I get an error with the line:

my_storage_cell = mat2cell(my_storage_mat2, ones(size(my_storage_mat,1),1),ones(size(my_storage_mat,2)),1);

It says: 'Error using mat2cell

Input arguments, D1 through D2, should be vectors.'

I'm a bit confused as to what this means

I am sorry I made error with the brackets position. Try this:

my_storage_cell = mat2cell(my_storage_mat,ones(size(my_storage_mat,1),1),ones(size(my_storage_mat,2),1));
