+\section{Modfied Bessel function of first order}
+The modified Bessel function of first order is defined as
+%
+\begin{align}
+I_\nu(x) &= \left(\frac12 x\right)^\nu
+ \sum\limits_{k=0}^{\infty} \frac{{\left(\frac14 x^2\right)}^k}{k!\Gamma(\nu+k+1)}
+\end{align}
+%
+\noindent The syntax of the macro is
+
+\begin{BDef}
+\Lcs{psModBessel}\OptArgs\Largb{xStart}\Largb{xEnd}
+\end{BDef}
+
+The only valid optional argument for the function is \Lkeyword{nue}, which
+is preset to 0, it shows $I_0$.
