v?Unpack

Copies elements of a vector with unit increment to an array with specified indexing.

Syntax

vsUnpackI( n, a, y, incy );

vsUnpackV( n, a, y, iy );

vsUnpackM( n, a, y, my );

vdUnpackI( n, a, y, incy );

vdUnpackV( n, a, y, iy );

vdUnpackM( n, a, y, my );

vcUnpackI( n, a, y, incy );

vcUnpackV( n, a, y, iy );

vcUnpackM( n, a, y, my );

vzUnpackI( n, a, y, incy );

vzUnpackV( n, a, y, iy );

Input Parameters

Name	Type	Description
n	const MKL_INT	Specifies the number of elements to be calculated.
a	const float* for vsUnpackI, vsUnpackV, vsUnpackM const double* for vdUnpackI, vdUnpackV, vdUnpackM const MKL_Complex8* for vcUnpackI, vcUnpackV, vcUnpackM const MKL_Complex16* for vzUnpackI, vzUnpackV, vzUnpackM	Specifies the pointer to an array of size at least `n` that contains the input vector a.
incy	const MKL_INT for vsUnpackI, vdUnpackI, vcUnpackI, vzUnpackI	Specifies the increment for the elements of `y`.
iy	const int* for vsUnpackV, vdUnpackV, vcUnpackV, vzUnpackV	Specifies the pointer to an array of size at least `n` that contains the index vector for the elements of `a`.
my	const int* for vsUnpackM, vdUnpackM, vcUnpackM, vzUnpackM	Specifies the pointer to an array of size at least `n` that contains the mask vector for the elements of `a`.

Output Parameters
