5 Arguments

1: $\mathbf{rkappa}$ – double Input

On entry: the argument $\kappa$ of the function.

Constraint: $0.01\le \mathbf{rkappa}\le 10.0$.

2: $\mathbf{beta2}$ – double Input

On entry: the argument ${\beta }^2$ of the function.

Constraint: $0.0\le \mathbf{beta2}\le 1.0$.

3: $\mathbf{mode}$ – Integer Input

On entry: if $\mathbf{mode}=0$, g01muc is to be called after the call to g01zuc. Otherwise, g01euc is to be called.

4: $\mathbf{xl}$ – double * Output

On exit: $x_l$, a threshold value below which ${\varphi }_V\left(\lambda \text{;}\kappa ,{\beta }^2\right)$ will be set to zero by g01muc and ${\Phi }_V\left(\lambda \text{;}\kappa ,{\beta }^2\right)$ will be set to zero by g01euc if $\lambda <x_l$.

5: $\mathbf{xu}$ – double * Output

On exit: $x_u$, a threshold value above which ${\varphi }_V\left(\lambda \text{;}\kappa ,{\beta }^2\right)$ will be set to zero by g01muc and ${\Phi }_V\left(\lambda \text{;}\kappa ,{\beta }^2\right)$ will be set to unity by g01euc if $\lambda >x_u$.

6: $\mathbf{comm\_arr}\left[322\right]$ – double Communication Array

On exit: this argument should be passed unchanged to g01euc or g01muc.

7: $\mathbf{fail}$ – NagError * Input/Output

The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).

6 Error Indicators and Warnings

NE_ALLOC_FAIL

Dynamic memory allocation failed.
See Section 3.1.2 in the Introduction to the NAG Library CL Interface for further information.

NE_BAD_PARAM

On entry, argument $〈\mathit{\text{value}}〉$ had an illegal value.

NE_INTERNAL_ERROR

An internal error has occurred in this function. Check the function call and any array sizes. If the call is correct then please contact NAG for assistance.
