    datatype_icon

    x

    The input argument.

    Default: 0

    datatype_icon

    n

    The exponent parameter.

    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

    En(x)

    Value of the exponential integral function.

    datatype_icon

    error out

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

    Algorithm for Computing the Exponential Integral Function

    The following equation defines the exponential integral function.

    E ( x , n ) = 1 t n e x t d t

    The following intervals for the input values define the exponential integral function.

    n { 0 , 1 , 2 , ... } , x [ 0 , )

    This node supports the entire domain of this function that produces real-valued results. For any nonnegative integer value of order n, the function is defined for nonnegative real values of x.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
