At least confusing documentation CMKL 8.1

In the CMKL 8.1 manual, page 153, description of ?herk routine.

One can read

---

a is an n-by-k matrix in the first case and a n-by-k matrix in the second case.

---

on the next page

---

a

COMPLEX for cherk

DOUBLE COMPLEX for zherk

Array, DIMENSION (lda, ka), where ka is k when trans = 'N' or 'n', and is n otherwise. Before entry with trans = 'N' or 'n', the leading n-by-k part of the array a must contain the matrix a, otherwise the leading n-by-k part of the array a must contain the matrix a.

However in MKL 8.0.1 documentation (page 151) the same things are explained as

---

a is an n-by-k matrix in the first case and a k-by-n matrix in the second case.

a

COMPLEX for cherk

DOUBLE COMPLEX for zherk

Array, DIMENSION (lda, ka), where ka is k when trans = 'N' or 'n', and is n otherwise. Before entry with trans = 'N' or 'n', the leading n-by-k part of the array a must contain the matrix a, otherwise the leading k-by-n part of the array a must contain the matrix a.

MKL documentation agrees with the description of zherk from
