vdPackM( n, a, ma, y );

vcPackI( n, a, inca, y );

vcPackV( n, a, ia, y );

vcPackM( n, a, ma, y );

Input Parameters

Name	Type	Description
n	const MKL_INT	Specifies the number of elements to be calculated.
a	const float* for vsPackI, vsPackV, vsPackM const double* for vdPackI, vdPackV, vdPackM const MKL_Complex8* for vcPackI, vcPackV, vcPackM const MKL_Complex16* for vzPackI, vzPackV, vzPackM	Specifies pointer to an array that contains the input vector a. The arrays must be: for v?PackI, at least`(1 + (n-1)*inca)` for v?PackV, at least `max( n,max(ia[j]) ), j=0, …, n-1` for v?PackM, at least `n`.
inca	const MKL_INT for vsPackI, vdPackI, vcPackI, vzPackI	Specifies the increment for the elements of `a`.
ia	const int* for vsPackV, vdPackV, vcPackV, vzPackV	Specifies the pointer to an array of size at least `n` that contains the index vector for the elements of `a`.
ma	const int* for vsPackM, vdPackM, vcPackM, vzPackM	Specifies the pointer to an array of size at least `n` that contains the mask vector for the elements of `a`.
