Let's say that value is you computed value, then you can create a folder in another library with name equals value using following code:

SPWeb web=SPContext.Current.Web; //just for example

var libUrl="host_relative_url_to_lib";
var docsLibrary = (SPDocumentLibrary)web.GetList(libUrl);
var libraryFolders = docsLibrary.RootFolder.SubFolders; //get all folders in lib
libraryFolders.Add(libUrl + "/" + value); //create a folder with name value
docsLibrary.Update(); //commit changes
