Importing unequal text from text file

I've got a file with the following format

if true
"abc","def","ada","bla"
"F52","L33"
.
.
.
end

with more lines following, generally all with a different number of " " entries per line.

So far I was able to import the file with textscan but it gets saved into a single column. I need each line to be a row and the strings inside the "" to be col entries. I think I can work with multiple arrays(one each line) or with an array filled with NaNs to fill the empty spaces, but have no idea how to separate the file after import

cellfun( @(S) regexp(S, ',', 'split').', regexp(fileread('YourFile.txt'), '\n', 'split'), 'uniform', 0 )

This should give you columns across and rows down.

fid = fopen('file.txt');
res={};
while ~feof(fid)
res{end+1,1} =fgetl(fid);
end
fclose(fid);
a=regexp( res,'(?<=")[^",]+(?=")','match')
n=cellfun(@numel,a)
for k=1:numel(a)
  out(k,1:n(k))=a{k};
end
out
