Out of memory issue

I am getting error,while Loading abc.csv file of 16567kb size,as Out of memory, I have Intel core2duo,3 ghz,3GB RAM,,please help me,, I want to convert .csv file to .mat file by loading it in workspace

[per isakson]

Some questions:

• which OS, Windows7?
• which Matlab release?
• are other programs running?
• size of swap file?
• what function do you use to "load" the file?

What does

    memory

return?

That's a pretty small file. Your computer, even with only 3 GB of memory should be able to handle a 16 MB file I would think. Can you paste the full error message here (all the red text)?

For large CSV files you are less likely to run into memory issues if you read it line by line, for example:

nFile = 'file.csv';
[fid, message] = fopen(nFile,'r');
i=1;
numlines = str2double(perl('Countlines.pl', nFile));

while 1
      tline = fgetl(fid);
      if ~ischar(tline), break, end

        comma = findstr(tline,',');

        if i == 1
            numComma =  length(comma);
            body_data = cell(numlines, numComma+1); % pre-allocate
        end

        body_data{i,1} = tline(1:comma(1)-1);
        body_data{i,numComma+1} = tline(comma(end)+1:end);

        for nData = 1:numComma-1
            body_data{i,nData+1} = tline(comma(nData)+1:comma(nData+1)-1);
        end
        i = i + 1;
  end
  fclose(fid);

Where the perl script simply contains:

while(<>){};
print $.,"\n",
