This function can be used to find the mean value for all the cells found within the defined region of a grid (all cell values are added together and then divided by the total number of cells that make the region), as shown in the image below:
ds_grid_get_mean(index, x1, y1, x2, y2);
| Argument | Type | Description |
|---|---|---|
| index | DS Grid | The index of the grid. |
| x1 | Real | The left cell column of the region. |
| y1 | Real | The top cell row of the region. |
| x2 | Real | The right cell column of the region. |
| y2 | Real | The bottom cell row of the region. |
val = ds_grid_get_mean(grid, 0, 0, 5, 5)
The above code will set the variable "val" to the mean value contained within the given region of the DS grid indexed in the variable "grid".
