Inputs/Outputs

  • cdbl.png x

    x is the input argument. If x is negative, the VI uses the absolute value of x.

  • cdbl.png a

    a is the first parameter of the Tricomi function.

  • cdbl.png b

    b is the second parameter of the Tricomi function.

  • idbl.png U(x, a, b)

    U(x, a, b) returns the value of the Tricomi function.

  • The Tricomi function U(x, a, b) is a solution of the following differential equation:
