A diagram showing a grid pattern with labeled points representing values, specifically \(u_{i-1, j}\), \(u_{i, j-1}\), \(u_{i, j}\), \(u_{i+1, j}\), and \(u_{i, j+1}\).

  • The image displays a structure resembling a point on a two-dimensional grid, suggesting a discrete function or PDE evaluation.
  • The coordinates are labeled on both the horizontal and vertical axes, indicating indices such as \(i-1\), \(i\), and \(i+1\) horizontally, and \(j-1\), \(j\), and \(j+1\) vertically.
  • Five specific points are marked on this grid, connected by implied axes or lines, forming a cross shape centered at the point labeled \(u_{i, j}\).
  • These labeled points are: \(u_{i-1, j}\) (to the left of the center point), \(u_{i+1, j}\) (to the right), \(u_{i, j-1}\) (below), and \(u_{i, j+1}\) (above), in addition to the central point \(u_{i, j}\).
