running command line using matlab

Question

I want to run the following command line

'C:\Program Files\CloudCompare>CloudCompare -o C:\CloudComparetest\test.bin -SS SPATIAL 0.1'

It works well ( see image) when I follow this way:

window-->cmd and type it directly there.

But I need to run this command inside matlab job. Online search gives me this pattern to run simple commands:

It works:

     command = 'C:\Program Files\CloudCompare\CloudCompare.exe';
     [status,cmdout] = system(command)
status=0;

But trying this gives me errors: (I know it is not standard dos command...may be any other solution.

    %  command = 'C:\Program Files\CloudCompare>CloudCompare -o C:\CloudComparetest\test.bin -SS SPATIAL 0.1';
    %  status = dos(command)
status=1;

I also tried

%  command = 'C:\Program Files\CloudCompare\CloudCompare -o C:\CloudComparetest\test.bin -SS SPATIAL 0.1';
%  status = dos(command)

status=1;

Error: while running cloud.bat

Either the command is not correct or can not be found.

 dos('"C:\MyPHDCODE\COLOR_SCANS\cloud.bat"')
C:\MyPHDCODE\Chapter5\COLORIMAGES>C:\Program Files\CloudCompare\CloudCompare -o C:\CloudComparetest\test.bin -SS SPATIAL 0.1 pause  
Der Befehl "C:\Program" ist entweder falsch geschrieben oder 
konnte nicht gefunden werden.

Note you have a space in your path name, and a >. Replace > with \ and enclose the command in "", this will let cmd run the command correctly (if there are no other errors)

Put this in a text file called cloud.bat:
"C:\Program Files\CloudCompare\CloudCompare" -o C:\CloudComparetest\test.bin -SS SPATIAL 0.1 pause

(SPATIAL 0.1 should be on the same line as the rest, pause on a new line)

Then call cloud.bat from the dos command. You should place cloud.bat in your current MatLab directory.

EDIT: what I meant here is that you should call cloud.bat from MatLab, I can see that it can be misunderstood.

When this is run you can see any error messages from CloudCompare.

i tried ''C:\Program Files\CloudCompare\CloudCompare -o C:\CloudComparetest\test.bin''' but no sucess'''. It didn't work.

Is it the correct path? To test, you could put the command in a bat-file, followed by pause, call the bat from matlab, then you could see the error message from cmd

i don't understand bat-file concept. I think problem is space. I donot know how to finish it.

When I look at your examples that work, you use different commands (dos and system), but they should both do the same. The second example is clearly wrong, > is a redirect character, not te be used in a path. Your command window example does not include the -SS switch?

You still should use "" around the path+command, as shown in my edited cloud.bat example. The error you get means that the command interpreter thinks c:\program is a command. It breaks because of the space in program files. "" tells the command interpreter to use the complete string as the command
