| dm | - The mesh, with coordinate maps defined either by a PetscDS for the coordinate DM (see DMGetCoordinateDM()) or implicitly by the coordinates of the corner vertices of the cell: as an affine map for simplicial elements, or as a multilinear map for tensor-product elements | |
| cell | - the cell whose map is used. | |
| numPoints | - the number of points to locate | |
| realCoords | - (numPoints x coordinate dimension) array of coordinates (see DMGetCoordinateDim()) |
| refCoords | - (numPoints x dimension) array of reference coordinates (see DMGetDimension()) |
