LINE_GRID
Grid of Points Inside a Line Segment in 1D {#line_grid-grid-of-points-inside-a-line-segment-in-1d align="center"}
LINE_GRID is a C++ library which generates a grid of points over the interior of a line segment in 1D.
The 1D line segment is the set of points X such that:
A <= X <= B
The parameters are:
- N, the number of points;
- A, B, the left and right endpoints;
- C, one of 5 choices for centering the grid.
The centering options allow the user to control the centering of the equally spaced points. This is easiest to illustrate if we assume A = 0 and B = 1. Then, using N = 4, the centering options will produce 4 equally spaced points as follows:
- 1: 0, 1/3, 2/3, 1 (include endpoints)
- 2: 1/5, 2/5, 3/5, 4/5 (do not include endpoints)
- 3: 0, 1/4, 2/4, 3/4 (do not include right endpoint)
- 4: 1/4, 2/4, 3/4, 1 (do not include left endpoint)
- 5: 1/8, 3/8, 5/8, 7/8 (half spacing at the ends)
