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

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.
