-<p>Function of two variables.</p>
-<p>TODO: 1) Technically, it could have a common parent (e.g. <code><a class="el" href="classbdm_1_1fnc.html" title="Class representing function  of variable  represented by rv.">fnc</a></code> ) with other functions. For now, we keep it as it is. 2) It could be generalized into multivariate form, (which was original meaning of <code><a class="el" href="classbdm_1_1fnc.html" title="Class representing function  of variable  represented by rv.">fnc</a></code> ). </p>

+Function of two variables.<p>
+TODO: 1) Technically, it could have a common parent (e.g. <code><a class="el" href="classbdm_1_1fnc.html" title="Class representing function  of variable  represented by rv.">fnc</a></code> ) with other functions. For now, we keep it as it is. 2) It could be generalized into multivariate form, (which was original meaning of <code><a class="el" href="classbdm_1_1fnc.html" title="Class representing function  of variable  represented by rv.">fnc</a></code> ). <hr><h2>Member Function Documentation</h2>
