# ?gesd2d

Takes a general rectangular matrix and sends it to the destination process.

## Syntax

call igesd2d( icontxt, m, n, a, lda, rdest, cdest )

call sgesd2d( icontxt, m, n, a, lda, rdest, cdest )

call dgesd2d( icontxt, m, n, a, lda, rdest, cdest )

call cgesd2d( icontxt, m, n, a, lda, rdest, cdest )

call zgesd2d( icontxt, m, n, a, lda, rdest, cdest )

## Input Parameters

icontxt | INTEGER. Integer handle that indicates the context.
m, n, a, lda | Describe the matrix to be sent. See Matrix Shapes for details.
rdest | INTEGER. The process row coordinate of the process to send the message to.
cdest | INTEGER. The process column coordinate of the process to send the message to.

## Description

This routine takes the indicated general rectangular matrix and sends it to the destination process located at {RDEST, CDEST} in the process grid. Return from the routine indicates that the buffer (the matrix A) may be reused. The routine is locally-blocking, that is, it will return even if the corresponding receive is not posted.
