passing filenames to a dos command

I would like to use an DOS executable command. The command requires file input and output names.

I cannot figure out how to pass the filenames (which are characters in the Matlab program).

For example the executable I want to run is "dcmdjpeg", so I have tried using

dos('.\dcmdjpeg FileIn FileOut'), but offcourse once I have the apostrophes DOS does not know what FileIn and FIleOut are.

Ive also tried

eval('!.\dcmdjpeg' FilNamIn FilNamOut);

Again this doesnt work.

just to add a bit more info. If I try

status=dos(['.\dcmdjpeg ', FilNam1 FilNam2]);

then I get the error

$dcmtk: dcmdjpeg v3.6.0 2011-01-06 $

dcmdjpeg: Decode JPEG-compressed DICOM file

error: Missing parameter dcmfile-out

To pass the filenames to the dos command, you need to properly construct the command string to include the file names.

Here's how you can do it:

% Replace these with your actual file names
FileIn = 'input_file_name';
FileOut = 'output_file_name';

command = sprintf('.\\dcmdjpeg %s %s', FileIn, FileOut);
output = dos(command);

Where "sprintf" is a string formatter, you can read more about it here: sprintf

Hope it helps!

See if the system function will do what you want.
