writecell errors with nested cells

I have a large variable that I want to export out of Matlab;

Name Size Bytes Class

NewDataSet2 756071x9 1167474054 cell

When I try to export it using:

writecell(NewDataSet2,'myDataFile.csv')

I get this error:

Error using writecell (line 117)

Nested cell arrays are not supported.

Any ideas on how to get this variable out of matlab and into a file (such as a text or excel file)?

It depends on what the contents of the cell elements is. Posting just the size does not allow to know this. Perhaps all you need is:

data = cell2mat(NewDataSet2)

Unforuntately, that does not work:

Error using cell2mat (line 45)

All contents of the input cell array must be of the same data type.

How can I determine the contents of each cell?

@Jessica: Are you sure that you have to store such a large set of data in a cell array? This is rather inefficient. Please post a small example of the data. Then suggesting a solution is not based on pure guessing only.

If "determine the contents" means to get the class of the data:

cellfun('isclass', C, 'double')
cellfun(@class, C, 'UniformOutput', false)
