Is it possible to get a register form calling a function in Wordpress

A simple question, I cannot really find it on StackOverflow.

It is possible to get the login form from WordPress by calling the wp_login_form() function.
But is there also a function you can call to get a registration form without doing a lot of coding?

Not sure what you are asking - from what you ask I guess you want to

1 call the Wordpress login form from outside Wordpress so you can log in to Wordpres (Admin?)
2 at some point call a Wordpress registration form so visitors can register as members ?
