<title>Description</title>
<para>
This is an Octave function.
This function computes the generalized Marcum Q function of order m with noncentrality parameter a and argument b.
The third argument m is the order, which by default is 1.
The fourth argument tol is the tolerance, which by default is eps.
If input arguments are vectors which correspond in size and degree, the output is a table of values.
This function calculates Marcum’s Q function using the infinite Bessel series, which is truncated when the relative error is less than the specified tolerance.
