I'm trying to use "sprintf" as follows:

command=sprintf('"C:\Program Files\Computers and Structures\SAP2000 19\SAP2000.EXE"  "G:\Desktop\modeling\Sap model thesis\test\Wharf Model %d.0.sdb"  /R /C',v);

But I'm getting this warning: Escaped character '\P' is not valid. See 'doc sprintf' for supported special characters.

Although I'm not trying to write any special character (except for %d). How can I use the slash character (\) without considering it a special character and without getting any warning?

Thanks.

在 MATLAB Online 中打开

command = sprintf('%s%d%s', '"C:\Program Files\Computers and Structures\SAP2000 19\SAP2000.EXE"  "G:\Desktop\modeling\Sap model thesis\test\Wharf Model ', v, '.0.sdb"  /R /C');

or

command = sprintf('"C:\\Program Files\\Computers and Structures\\SAP2000 19\\SAP2000.EXE"  "G:\\Desktop\\modeling\\Sap model thesis\\test\\Wharf Model %d.0.sdb"  /R /C',v);
