GAMMAINC

 

 The incomplete gamma function.

  Y = GAMMAINC(X,A) evaluates the incomplete gamma function at all

  the elements of X.  X must be real.  A must be a real scalar.

  gammainc(x,a) = (integral from 0 to x of t^(a-1) exp(-t) dt)/gamma(a).

  Note that gammainc(x,a) approaches 1 as x approaches infinity.
