txt file to cell array to text file

Dear all,

I have a matrix txt file with 384 rows and 12 columns (tab-formatted). Each column can have either numeric or string data. I want to import the matrix so that I can make loops and if-then opeations on single columns (changing numbers with strings, or execute math operations, for example).

I imported my data using tdfread and then convert it into a cellarray with struct2cell:

B = tdfread (filename, '\t');
D = struct2cell(B);

This would give me D=<12x1cell>

Now my questions:

(1) Is this procedure the best one?

(2) How can I loop within one of the nested cells, let's say n. 3 - which would correspond to column 3 in the orginal txt matrix?

(2) How can I then export the new modified cell-array to a txt file once again? Would fprintf be a good solution?

Sorry to be dumb!

Any help appreciated.

Best,

Udiubu

3) I have previously used the following:

save example.txt D -ascii

This saves the array into a text file called example.txt.
