# DMDACoor2d
Structure for holding 2d (x and y) coordinates when working with `DMDA` 
## Synopsis
```
.vb
DMDACoor2d **coors;
Vec      vcoors;
DM       cda;
DMGetCoordinates(da,&vcoors);
DMGetCoordinateDM(da,&cda);
DMDAVecGetArray(cda,vcoors,&coors);
DMDAGetCorners(cda,&mstart,&nstart,0,&m,&n,0)
for (i=mstart; i<mstart+m; i++) {
for (j=nstart; j<nstart+n; j++) {
x = coors[j][i].x;
y = coors[j][i].y;
......
