Description

The routine unpacks nm Compact format matrices A_c from array ap into standard (row- or column-major, pointer-to-pointer) format in array A.

Input Parameters

layout

Specifies whether two-dimensional array storage is row-major (MKL_ROW_MAJOR) or column-major (MKL_COL_MAJOR).

rows

The number of rows of A; rows >= 0.

columns

The number of columns of A; columns >= 0.

lda

Leading dimension of A.

layout = MKL_COL_MAJOR	lda must be at least max (1,rows).
layout = MKL_ROW_MAJOR	lda must be at least max (1,columns).

ap

Array storing the compact format of input matrices A_c. See Compact Formator mkl_get_format_compact for details.

layout = MKL_COL_MAJOR	ap has size ldap*columns*nm.
layout = MKL_ROW_MAJOR	ap has size ldap*rows*nm.

ldap

Leading dimension of of A_c.

layout = MKL_COL_MAJOR	ldap must be at least max (1,rows).
layout = MKL_ROW_MAJOR	ldap must be at least max (1,columns).

Note

The values of ldap used in mkl_?geunpack_compact must be consistent with the values used in mkl_?get_size_compact and mkl_?gepack_compact.

format

Specifies the format of the compact matrices. See Compact Format ormkl_get_format_compact for details.

nm

Total number of matrices that will be stored in Compact format.

Output Parameters

a

A standard format (row- or column-major, pointer-to-pointer) array, storing nm output A matrices.

layout = MKL_COL_MAJOR	a has size lda*columns*nm.
layout = MKL_ROW_MAJOR	a has size lda*rows*nm.
