Function Documentation

zsl_vec_copy()

int zsl_vec_copy	(	struct zsl_vec *	vdest,
		struct zsl_vec *	vsrc
	)

Copies the contents of vector 'vsrc' into vector 'vdest'.

Parameters

vdest	Pointer to the destination vector data will be copied to.
vsrc	Pointer to the source vector data will be copied from.

Returns

0 on success, and non-zero error code on failure

zsl_vec_from_arr()

int zsl_vec_from_arr	(	struct zsl_vec *	v,
		zsl_real_t *	a
	)

Converts an array of values into a vector. The number of elements in array 'a' must match the number of elements in vector 'v'. As such, 'v' should be previously initialised with an appropriate value assigned to v.sz.

Parameters

v	The vector that the contents of array 'a' should be assigned to. The v.sz value must match the number of elements in 'a', meaning that the vector should be initialised before being passed in to this function.
a	Pointer to the array containing the values to assign to 'v'. The array will be read v.sz elements deep.

Returns

0 on success, and non-zero error code on failure

zsl_vec_init()

int zsl_vec_init

(

struct zsl_vec *

v

)

Initialises vector 'v' with 0.0 values.

Parameters

v	Pointer to the zsl_vec to initialise/clear.

Returns

0 on success, and non-zero error code on failure
