How can I save 3d arrays in a cell array?

I have two 3d arrays (138x155x24) but I can't put it in only cell array. How can I do that?

Thanks for any help!

You certainly can put 3D arrays into a cell array. Please post what variables you have and also post the code you are currently trying, and what you want to get as a result.

Sorry, I forgot.

I have seven days with hours values of wind velocity. This variable has 24 data array (lon x lat), with dimension longitude x latitude x hours.

My problem is: Using ncread, save arrays of wind velocity (lon x lat) in X-axis (u) and Y-axis (v) in a cell array. Each line have to show the 24 matrix of data of one day.

data = cell(1,2);
for K = 1 : 2
  data{K} = rand(138, 155, 24);
end

and now data is a cell array with two entries, each containing a 138 x 155 x 24 array.

Thank you!

Should I use exactly this command?

And do you know how can I plot it?

[Walter Roberson]

dinfo = dir('*.nc');
nfile = length(dinfo);
data = cell(nfile, 1);
for K = 1 : nfile
   thisfile = dinfo(K).name;
   data{K} = mat2cell( ncread(thisfile, 'velocity'), 3 );  %split on 3rd dimension
 end

This would give you a cell array, data, with one entry per file. Each entry would itself be a cell array of length 24, each containing one lon x lat entry.

Note: you might find that you get lat x lon entries instead of lon x lat. If so then

     data{K} = mat2cell( permute(ncread(thisfile, 'velocity'), [2 1 3], 3 );  %split on 3rd dimension
