?trrv2d

Receives a message from the process into the trapezoidal matrix.

Syntax

call itrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )

call strrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )

call dtrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )

call ctrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )

call ztrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )

Input Parameters

icontxt	INTEGER. Integer handle that indicates the context.
uplo, diag, m, n, lda	Describe the matrix to be sent. See Matrix Shapes for details.
rsrc	INTEGER. The process row coordinate of the source of the message.
csrc	INTEGER. The process column coordinate of the source of the message.

Output Parameters

a	An array of dimension `(lda,n)` to receive the incoming message into.

Description

This routine receives a message from process {RSRC, CSRC} into the trapezoidal matrix A. This routine is globally-blocking, that is, return from the routine indicates that the message has been received into A.
