| integer(kind=int32), | public, | parameter | :: | POINCARE_ONE_SIDED_FROM_BACK | = | 2 |
A one-sided Poincare section will be computed where the algorithm only retains intersection points where the trajectory approaches the sectioning plane from the back (the side opposite the plane normal). |
| integer(kind=int32), | public, | parameter | :: | POINCARE_ONE_SIDED_FROM_FRONT | = | 1 |
A one-sided Poincare section will be computed where the algorithm only retains intersection points where the trajectory approaches the sectioning plane from the front (the side of the plane normal). |
| integer(kind=int32), | public, | parameter | :: | POINCARE_TWO_SIDED | = | 0 |
A two-sided Poincare section will be computed. In this section, the algorithm does not care whether the trajectory approaches the sectioning plane from the front or the back of the plane (defined by the plane normal). It simply returns any intersection point. |
Generates a Poincare map by determining the intersections of the supplied trajectory with the specified plane.

An integer flag denoting which approach to use when computing the section. The acceptable values are as follows. |
An N-by-3 matrix containing the x, y, and z coordinates of each of the N intersection points in the first, second, and third columns respectively.
