Ker
Real Kelvin function of the second kind.
 
Loading        LOADSUB ALL FROM "KELVIN.HTS"
or LOADSUB FROM "MATHLIB.HTS"
 
Usage                        REAL X,Y
Y=FNKer(X)
 
Description                
FNKer returns the value of the real Kelvin function of the second kind of the value x. Although ker(x) is defined for all values of x except zero, values of x near zero may produce results greater than MAXREAL, the largest value representable. Note that sometimes Kelvin functions are written with an order, as in ker3(x). In this notation, the function FNKer returns the value of ker0(x).
 
Errors                
FNKer causes an HTBasic error if its argument is not of type REAL, if x is negative or zero, or if the value returned would be larger than MAXREAL.
