    x

    The real input of the incomplete gamma function. x must be nonnegative.

    Default: 0

    datatype_icon

    a

    The upper limit of the regularized incomplete gamma function.

    Default: Positive infinity

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    g(x, a)

    The result of the regularized incomplete gamma function for the given values of x and a.

    error out

    Error information. The node produces this output according to standard error behavior.

    Algorithm for Evaluating the Regularized Incomplete Gamma Function

    The following equation defines the regularized incomplete gamma function.

    Γ ( x , a ) = 1 Γ ( x ) 0 a t x 1 e t d t

    The following intervals for the input values define the function.

    a ( 0 , ) , x [ 0 , )

    The following illustration shows the regularized incomplete gamma functions with a = 1, 2, 3, and 4 from top to bottom.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
