Detailed Description

Functions used to compare or verify vectors.

Function Documentation

zsl_vec_contains()

int zsl_vec_contains	(	struct zsl_vec *	v,
		zsl_real_t	val,
		zsl_real_t	eps
	)

Checks if vector v contains val, returning the number of occurences.

Parameters

v	The vector to check.
val	The value to check all coefficients for.
eps	The margin for floating-point equality (ex. '1E-5').

Returns

The number of occurences of val withing range eps, 0 if no matching occurences were found, or a negative error code.

zsl_vec_is_equal()

bool zsl_vec_is_equal	(	struct zsl_vec *	v,
		struct zsl_vec *	w,
		zsl_real_t	eps
	)

Checks if two vectors are identical in size and content.

Parameters

v	The first vector.
w	The second vector.
eps	The margin for floating-point equality (ex. '1E-5').

Returns

true if the two vectors have the same size and the same values, otherwise false.

zsl_vec_is_nonneg()

bool zsl_vec_is_nonneg

(

struct zsl_vec *

v

)

Checks if all elements in vector v are >= zero.

Parameters

v	The vector to check.

Returns

true if all elements in 'v' are zero or positive, otherwise false.

Definition at line 405 of file vectors.c.

zsl_vec_sort()

int zsl_vec_sort	(	struct zsl_vec *	v,
		struct zsl_vec *	w
	)

Sorts the values in vector v from smallest to largest using quicksort, and assigns the sorted output to vector w.

Parameters

v	The unsorted, input vector.
w	The sorted, output vector.

Returns

0 if everything executed properly, otherwise a negative error code.
