[in] | x | Array over which to compute the statistics. Must not equal NULL if the length, 'n', is greater than 0. |
[in] | n | Length of the array 'x'. |
If x is NULL or n <= 0, then this routine generates an error and exits the application.

size_t | n | ||
) |
[in] | x | Array over which to compute the statistics. Must not equal NULL if the length, 'n', is greater than 0. |
[in] | n | Length of the array 'x'. |
If x is NULL or n <= 0, then this routine generates an error and exits the application.

VALTYPE VTMANGLE() CalcMin | ( | const VALTYPE * | x, |
size_t | n | ||
) |
[in] | x | Array over which to compute the statistics. Must not equal NULL if the length, 'n', is greater than 0. |
[in] | n | Length of the array 'x'. |
If x is NULL or n <= 0, then this routine generates an error and exits the application.

VALTYPE * | p_min, | ||
VALTYPE * | p_max, | ||
VALTYPE * | p_mean | ||
) |
[in] | x | Array over which to compute the statistics. Must not equal NULL if the length, 'n', is greater than 0. |
[in] | n | Length of the array 'x'. |
[in,out] | p_min | Pointer to location in which to store the minimum value. If NULL, the minimum is not returned. |
[in,out] | p_max | Pointer to location in which to store the maximum value. If NULL, the maximum is not returned. |
[in,out] | p_mean | Pointer to location in which to store the mean value. If NULL, the mean is not returned. |
If n <= 0, this routine simple returns and leaves the variables *p_min, *p_max, *p_mean unchanged. Otherwise, if x is NULL, then this routine exits the application.

size_t | n, | ||
VALTYPE * | p_min, | ||
VALTYPE * | p_max, | ||
VALTYPE * | p_median | ||
) |
[in] | x | Array on which to compute statistics. Must not equal NULL if the length, 'n', is greater than 0. |
[in] | n | Length of x. |
[in,out] | p_min | Pointer to location in which to store the minimum value of the array x. If NULL, then the minimum is not returned. |
[in,out] | p_max | Pointer to location in which to store the maximum value of the array x. If NULL, then the maximum is not returned. |
[in,out] | p_medain | Pointer to location in which to store the median value of the array x. Must not equal NULL. |
This routine takes no action of n <= 0. If n > 0 and x is not equal to NULL, then this routine aborts.
