Find points on the boundary of a truncated sector.
Description
This routine determines the points on the boundary of a truncated sector, whose imaginary parts are equal to the elements in the vector w.
Syntax
pts=find_points(w,sector)Input arguments
| w | Vector of real numbers. |
| sector | Vector $[\alpha\ \xi\ \omega_c]$ characterizing the considered truncated sector (see display_sector for a complete description). The third parameter $\omega_c$ is optional. If omitted, its value is automatically computed so that $\beta=0$. |
Output argument
| pts | Points on the boundary of the considered sector, whose imaginary parts are equal to the elements in w. |
Example
w=[0 1 2];sector=[-1 0.5 1];pts=find_points(w,sector)display_sector(sector,pts);
