Airy function or it's derivative of the second kind (Real argument, allows derivative and scale).

Syntax
C#
Visual Basic
public static double Biry(double A, bool Derive, bool Scale, ref int Error);
Parameters
Parameters 
Description 
double A 
Defines complex value where BI or it's derivative should be evaluated. 
bool Derive 
If true, function will return Airy (BI) derivative instead of the actual Airy (BI) function. 
bool Scale 
If true, result function (BI) or it's derivative is scaled by Exp(-|z|*|z|), where z = z = (2/3)*(Z)^(3/2) 
ref int Error 
Returns error code after the calculation. Return values are:
  • 0, Normal return - Computation completed.
  • 1, input error - no computation.
  • 2, overflow - no computation; dreal(zta)- too large with Scaling=false.
  • 3, zabs(z) large - computation completed. Losses of signifcance by argument reduction produce less than half of machine accuracy.
  • 4, zabs(z) too large - no computation; complete loss of accuracy by argument reduction.
  • 5, error - no computation; algorithm termination condition not met.
 
Returns

the Airy function or it's derivative of the second kind (BI).
