<span class="emphasis"><em>cuserrnd</em></span> (continuous user-defined-distribution random generator) generates random values according to a continuous random distribution created by the user. In this case the shape of the distribution histogram can be drawn or generated by any GEN routine. The table containing the shape of such histogram must then be translated to a distribution function by means of GEN40 (see <a class="link" href="GEN40.html" title="GEN40">GEN40</a> for more details). Then such function must be assigned to the XtableNum argument of cuserrnd. The output range can then be rescaled according to the Xmin and Xmax arguments. cuserrnd linearly interpolates between table elements, so it is not recommended for discrete distributions (<a class="link" href="GEN41.html" title="GEN41">GEN41</a> and <a class="link" href="GEN42.html" title="GEN42">GEN42</a>).
