CELLWRITE

Cellwrite writes mixed cell array data to a CSV file.

Description

This function implements the basic functionallity of csvwrite but operates on cell arrays of mixed data (numeric and string) instead of arrays of numeric data.

CELLWRITE(FILENAME, C) writes the cell array C to FILENAME as comma separated values.

Performance tests on 1000 by 100 matrices of random numeric data show performance nearly identical to CSVWRITE.

• MATLAB release: MATLAB 6.5 (R13)

Works well. Just what I needed!

[Kyle Archie]

no idea why this is isn't already a standard function. Thanks!

[Adam N]

excellent! would be better if we could choose the delimiter i.e. tab, comma, semicolon, etc.
thanks!

[Thomas Heinz]

yes, why isn't it a standard function?! Thanks!

I have noticed that Matlab 7.5 needs a revision to cellwrite to work with cells:

fprintf(fid,'%s\n',file_line) should be
fprintf(fid,'%s\n',file_line{:})

[Ben Spivey]

the {:} addition is needed when the cell array has one layer of embedded cell arrays - the format that textscan provides.

This was terrific. I don't see why this WASN'T included with MATLAB originally, but it should definitely come standard.

Did just what I needed! Well done!

I've been using this for a while now and its great but...one of the tests for changing numbers into text needs adjusting for logicals...

I change:
if isnumeric(contents)

into

if isnumeric(contents) || islogical(contents)

Because the logical class is not including in isnumeric (helpfully). It may add a small speed hit, but it increases the robustness a little.

Thanks for the program though!

Thanks so much, this is a lifesaver. Great when working on Linux OS. I added one line to replace any comma already existing in the texts by '_' before writing contents. Important if you have chemical names in there.
...
elseif isempty(contents)
            contents = '';
        else
            contents=strrep(contents, ',' , '_' );
       end

Works great! I changed the 'w' to an 'a' in the fopen statement so that I could add lines to the csv in successive calls in a loop.

@Barry Williams:

I am just curious what made you give it four stars.
