nag_mip_opt_set("Initialize = h02dac", iopts, liopts, opts, lopts, &fail)

4  References

5  Arguments

1:    $\mathbf{optstr}$ – const char *Input

On entry: a string identifying the option to be set.

$\mathbf{Initialize}=\mathit{function\; name}$

Initialize the optional argument arrays iopts and opts for use with function $\mathit{function\; name}$, where $\mathit{function\; name}$ is the short name associated with the function of interest.

$\mathbf{Defaults}$

Resets all options to their default values.

$\mathit{option}=\mathit{optval}$

See Section 11 in nag_mip_sqp (h02dac) for details of valid values for option and optval. The equals sign ($=$) delimiter must be used to separate the option from its optval value.

optstr is case insensitive. Each token in the option and optval component must be separated by at least one space.

2:    $\mathbf{iopts}\left[\mathbf{liopts}\right]$ – IntegerCommunication Array

3:    $\mathbf{liopts}$ – IntegerInput

On entry: the length of the array iopts.

Constraint: unless otherwise stated in the documentation for a specific, supported, problem solving function, $\mathbf{liopts}\ge 200$.

4:    $\mathbf{opts}\left[\mathbf{lopts}\right]$ – doubleCommunication Array

5:    $\mathbf{lopts}$ – IntegerInput

On entry: the length of the array opts.

Constraint: unless otherwise stated in the documentation for a specific, supported, problem solving function, $\mathbf{lopts}\ge 100$.

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

The NAG error argument (see Section 3.6 in the Essential Introduction).

6  Error Indicators and Warnings

NE_ALLOC_FAIL

Dynamic memory allocation failed.
See Section 3.2.1.2 in the Essential Introduction for further information.

NE_BAD_PARAM

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

NE_INT

On entry, $\mathbf{liopts}=〈\mathit{\text{value}}〉$.
Constraint: $\mathbf{liopts}\ge 〈\mathit{\text{value}}〉$.

On entry, $\mathbf{lopts}=〈\mathit{\text{value}}〉$.
Constraint: $\mathbf{lopts}\ge 〈\mathit{\text{value}}〉$.

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.

An unexpected error has been triggered by this function. Please contact NAG.
See Section 3.6.6 in the Essential Introduction for further information.

NE_INVALID_FORMAT

On entry, could not convert the specified optval to an integer: $\mathbf{optstr}=〈\mathit{\text{value}}〉$.

On entry, could not convert the specified optval to a real: $\mathbf{optstr}=〈\mathit{\text{value}}〉$.

On entry, the expected delimiter ‘$=$’ was not found in optstr: $\mathbf{optstr}=〈\mathit{\text{value}}〉$.

NE_INVALID_OPTION

On entry, either the option arrays have not been initialized or they have been corrupted.

On entry, the optional argument in optstr was not recognized: $\mathbf{optstr}=〈\mathit{\text{value}}〉$.

NE_INVALID_VALUE

On entry, the optval supplied for the character optional argument is not valid.
$\mathbf{optstr}=〈\mathit{\text{value}}〉$.

On entry, the optval supplied for the integer optional argument is not valid.
$\mathbf{optstr}=〈\mathit{\text{value}}〉$.

On entry, the optval supplied for the real optional argument is not valid.
$\mathbf{optstr}=〈\mathit{\text{value}}〉$.

NE_NO_LICENCE

Your licence key may have expired or may not have been installed correctly.
See Section 3.6.5 in the Essential Introduction for further information.

NE_NOT_FUN_NAME

On entry, attempting to initialize the optional argument arrays but specified function name was not valid: $\text{name}=〈\mathit{\text{value}}〉$.
