K.fun | R Documentation |
Calculates the K.fun in terms of either m
(K.fun()
)
or k
(K.fun.k()
).
K.fun(m, strict=TRUE, maxiter=7, miniter=3)
m |
Real or complex parameter |
strict |
Boolean, with default |
maxiter |
Maximum number of iterations |
miniter |
Minimum number of iterations to guard against premature exit if an addend is zero exactly |
