Q = marcumq(a,b) computes the Marcum Q function of a and b, defined byQ(a,b)=∫b∞xexp(−(x2+a2)2) I0(ax) dxwhere a and b are nonnegative real numbers. In this expression, I0 is the modified Bessel function of the first kind of zero order.Q = marcumq(a,b,m) computes the generalized Marcum Q, defined byQ(a,b)=1am−1∫b∞xmexp(−(x2+a2)2)Im−1(ax) dxwhere a and b are nonnegative real numbers, and m is a positive integer. In this expression, Im–1 is the modified Bessel function of the first kind of order m–1.If any of the inputs is a scalar, it is expanded to the size of the other inputs.
