robustreadcsv

CSVREAD for files with varying number of cols.

Description

If you have a file that has more commas in some lines than others, this is for you.

It's very simple, but it may help some of you.

• MATLAB release: MATLAB 6.1 (R12.1)

Adding this code to the end of the function makes a variable for each column. The name is taken from the first (header) row

data = MM;
clear MM;
for i=1:size(data,2)
cmd = ['MM.' data{1,i} ' = data(2:end,' num2str(i) ');'];
eval(cmd);
end

This function is indeed really great, and robust.

I added 1 line to hugely boost performance by preallocating the output array "MM". To do this, just add this line right before the "for" loop:

MM=cell(length(M),max(cellfun(@length,regexp(M,','))));

Excellent reader, but consume too much memory for large files

[Dan Don]

Simple and effective

[Francis Pieraut]

Great! This function should be include by defalut in matlab. It works perfectly.

[Ricardo Pachon]

Indeed, it can help you! Perhaps you must add a few lines so it fits your needs, but it will work fine.
