Description
The
vslSSEditCP
 routine replaces pointers to the array of means, array of sums, cross-product matrix, and its storage format with values passed as corresponding parameters of the routine. See Table:
"Storage formats of a variance-covariance/correlation/cross-product matrix"
 for possible values of the
cp_storage
 parameter. If you pass a value of
NULL
 for a specific input parameter, the value of that parameter in the task descriptor is unchanged.

/cross-product
 matrices
Parameter
Description
VSL_SS_MATRIX_STORAGE_FULL
The array
cp
 contains all elements of the matrix stored sequentially,
row-by-row
:

    cp
    [0]
     contains
    c
    1, 1

    cp
    [1]
     contains
    c
    1, 2

    cp
    [
    p
     - 1]
     contains
    c
    1,
    p

    cp
    [
    p
    ]
     contains
    c
    2,1

    cp
    [
    p
    *
    p
     - 1]
     contains
    c
    p
    ,
    p

The size of array
cp
 is
p
*
p
.
VSL_SS_MATRIX_STORAGE_L_PACKED
The array
cp
 contains the lower triangular part of the symmetric matrix stored sequentially,
row-by-row
:

    cp
    [0]
     contains
    c
    1, 1

    cp
    [1]
     contains
    c
    2, 1

    cp
    [2]
     contains
    c
    2, 2

    and so on.

The size of the array is
p
*(
p
+ 1)/2.
VSL_SS_MATRIX_STORAGE_U_PACKED
The array
cp
 contains the upper triangular part of the symmetric matrix stored sequentially,
row-by-row
:

    cp
    [0]
     contains
    c
    1, 1

    cp
    [1]
     contains
    c
    1, 2

    cp
    [3]
     contains
    c
    1, 3

    and so on.

The size of the array is
p
*(
p
+ 1)/2.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
