Anything following a single slash *is not* part of HTTP_HOST, so you have to move the subdomain name to the RewriteRule. For use in .htaccess:

RewriteCond %{REQUEST_URI} ^/subdomain1 [OR]
RewriteCond %{REQUEST_URI} ^/subdomain2 [OR]
RewriteCond %{REQUEST_URI} ^/subdomain3 [OR]
RewriteCond %{REQUEST_URI} ^/subdomainN
RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com [NC]
RewriteRule ^([^/]+)/(.*) http://$1.mydomain.com/$2 [R=301,L] 

Very few webmasters need to use a rewrite like that; The more frequent request is for the opposite function, useful with wild-card DNS for hosting multiple subdomains under one hosting account. So just in case:

subdomain.mydomain.com OR www.subdomain.mydomain.com => www.mydomain.com/subdomain, using an internal (invisible) rewrite:

RewriteCond %{REQUEST_URI} !^/subdomain
RewriteCond %{HTTP_HOST} ^(www\.)?subdomain\.mydomain\.com [NC]
RewriteRule (.*) /subdomain/$1 [L] 

For use in httpd.conf, precede each RewriteRule pattern with a "/".

A more general solution, usable with any number of arbitrary subdomain subdirectories, is discussed in this recent thread, Rewrite arbitrary subdomains to subdirectories [webmasterworld.com].
