How do I save a cell array that has both text and numeric data?
显示 更早的评论
I have a data set where I would like to extract alphanumeric data to a text file. E.g. here is one 1x6 cell array:
37 0 240 0.436 'cat dog mouse' 10
I would like to save this data into a text file but I cannot do that with the fprintf command since it contains alphanumeric data. How do I do this?

Here's one way:
ca = {37, 0, 240, 0.436, 'cat dog mouse', 10}
fid = open(filename, 'wt'); % File on disk
% fid = 1; % Command window.
fprintf(fid, '%f, %f, %f, %f, %s, %d\n', ca{:});
close(fid);

You need %f for numbers with fractional parts. You can use %f for integers also but %d works for integers only and %d is what I use if I know for certain the numbers are pure integers. Using %d for fractional numbers won't work - you need %f for them.

I don't know. You could always try it. I think they recommend textscan() now instead of textread(). Or you could use fgetl() to get just one line and then use textscan() or sscanf() on just that line.
You might also be able to use importdata() or readtable(). See which function lets you read it in with the least fuss.
