Hello,

I know matlab script files don't accept filenames with many dots.

But my problem is different. I am trying to read a text file with csvread, and I get file not found error if the filename contains a dot other than the file extension separator.

I cannot rename these files because these files are generated and appended by another software. Renaming them breaks the updates.

How can I make csvread work?

Thanks

I am really in trouble. fopen fails to open if filename contains @ symbol or extra . other than the one before file extension. I have so many files to load with these symbols.

I also tried csvread and dlmread, same problem.

Is there any other way to load files in Matlab?

Thanks

csvread() is a wrapper around dlmread() which in turn is a wrapper around textscan(). You could use textscan() directly.

Could you give an example?

Also which operating system and MATLAB version are you using?

在 MATLAB Online 中打开

This works for me on R2012a 64bit

    >> fid = fopen( '@AAE-I_INDEX_S&P Custom_ABN AMRO Renewable.csv', 'r' );
    >> cac = textscan( fid, '%[^\n]' )
    cac = 
        {1x1 cell}
    >> cac{:}{:}
    ans =
    ?FROM 192.168.7.2:658161? 058 032 ...
    >>

and this too

    >> fid = fopen( 'AZO_NYSE_Autozone Inc..CSV', 'r' );
    >> cac = textscan( fid, '%[^\n]' )
    cac = 
        {1x1 cell}
    >> cac{:}{:}
    ans =
    ?FROM 192.168.7.2:658161? 058 032 055 ...
