Momeni Feyli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many recent high energy physics calculations involving charm and beauty invoke wave function at the origin (WFO) for the meson bound state. Uncertainties of charm and beauty quark masses and different models for potentials governing these bound states require a simple numerical algorithm for evaluation of the WFO's for these bound states. We present a simple algorithm for this propose which provides WFO's with high precision compared with similar ones already obtained in the literature. <p class="card-text"><strong>Keywords:</strong>
