Functions
oski_value_t *	array_Duplicate (const oski_value_t *x0, oski_index_t len)
	Returns a pointer to a newly allocated copy of the given array, or NULL on error.
void	array_Destroy (oski_value_t *x)
	Release previously allocated array.
int	array_CompareElems_NoAbort (const char *test_func, const oski_value_t *x, const oski_value_t *y, oski_index_t len)
	Compare elements of two arrays, and exit the program with an error code of 1 if the element-wise difference greater than len*(machine epsilon) detected.
void	array_CompareElems (const char *test_func, const oski_value_t *x, const oski_value_t *y, oski_index_t len)
	Compare elements of two arrays, and exit the program with an error code of 1 if the element-wise difference greater than len*(machine epsilon) is detected.
void	array_FillRandom (oski_value_t *x, oski_index_t n)
	Initialize an array with random values between -1 and 1.
oski_value_t *	array_CreateRandom (oski_index_t n)
	Allocate an array of random values between -1 and 1.
oski_value_t *	array_Create (oski_index_t n, oski_value_t val)
	Allocate an array with elements initialized to a particular value.
static int	compare_indvalpair (const void *pa, const void *pb)
void	array_SortIndValPairs (oski_index_t *ind, oski_value_t *val, oski_index_t n)
	Sorts an (index, value) pair of arrays.

Function Documentation

void array_CompareElems (  const char *  test_func, const oski_value_t *  x, const oski_value_t *  y, oski_index_t  len )

Compare elements of two arrays, and exit the program with an error code of 1 if the element-wise difference greater than len*(machine epsilon) is detected. Parameters: [in]  test_func  Name of the calling test function. [in]  x  Expected results. [in]  y  Observed/computed results. [in]  len  Length of the x and y arrays.

int array_CompareElems_NoAbort (  const char *  test_func, const oski_value_t *  x, const oski_value_t *  y, oski_index_t  len )

Compare elements of two arrays, and exit the program with an error code of 1 if the element-wise difference greater than len*(machine epsilon) detected. Parameters: [in]  test_func  Name of the calling test function. [in]  x  Expected results. [in]  y  Observed/computed results. [in]  len  Length of the x and y arrays.

void array_Destroy (  oski_value_t *  x  )

Release previously allocated array. Parameters: [in,out]  x  Array to destroy. Postcondition: x no longer usable.

oski_value_t* array_Duplicate (  const oski_value_t *  x0, oski_index_t  len )

Returns a pointer to a newly allocated copy of the given array, or NULL on error. Parameters: [in]  x0  Array to copy. [in]  len  Number of elements to copy from x0. Returns: A newly allocated copy of x0, or NULL on error.
