p?tranu
Transposes a distributed complex matrix.
Syntax
call pctranu(m, n, alpha, a, ia, ja, desca, beta, c, ic, jc, descc)
call pztranu(m, n, alpha, a, ia, ja, desca, beta, c, ic, jc, descc)

Description
The p?tranu routines transpose a complex distributed matrix. The operation is defined as
sub(C):=beta*sub(C) + alpha*sub(A)',
where:
alpha and beta are scalars,
sub(C) is an m-by-n distributed matrix, sub(C)=C(ic:ic+m-1, jc:jc+n-1).
sub(A) is a distributed matrix, sub(A)=A(ia:ia+n-1, ja:ja+m-1).
Input Parameters
- m
-
(global) INTEGER. Specifies the number of rows of the distributed matrix sub(C), m≥ 0.
- n
-
(global) INTEGER. Specifies the number of columns of the distributed matrix sub(C) , n≥ 0.
- alpha
-
(global)COMPLEX for pctranu
DOUBLE COMPLEX for pztranu
Specifies the scalar alpha.
- a
-
(local)COMPLEX for pctranu
DOUBLE COMPLEX for pztranu
Array, size (lld_a, LOCq(ja+m-1)). This array contains the local pieces of the distributed matrix sub(A).
- ia, ja
-
(global) INTEGER. The row and column indices in the distributed matrix A indicating the first row and the first column of the submatrix sub(A), respectively.
- desca
-
(global and local) INTEGER array of dimension 9. The array descriptor of the distributed matrix A.
- beta
-
(global)COMPLEX for pctranu
DOUBLE COMPLEX for pztranu
Specifies the scalar beta.
When beta is equal to zero, then sub(C) need not be set on input.
- c
-
(local)COMPLEX for pctranu
DOUBLE COMPLEX for pztranu
Array, size (lld_c, LOCq(jc+n-1)).
This array contains the local pieces of the distributed matrix sub(C).
- ic, jc
-
(global) INTEGER. The row and column indices in the distributed matrix C indicating the first row and the first column of the submatrix sub(C), respectively.
- descc
-
(global and local) INTEGER array of dimension 9. The array descriptor of the distributed matrix C.
Output Parameters
- c
-
Overwritten by the updated submatrix.
