Name: | gr_lift - a GRToolbox module |

Description: | Calculates the lift of an airfoil. Therefor the area between either one coherent curve or 2 curves of the same orientation is integrated. The area is calculated by calculating the formula: (x[n+1]-x[n])*(y[n+1]-y[n])/2 |

Synopsis: | -[pts points formath o v noc nof now skip f m c e i s l] -help For help on all options. |

Special Options: | -abs print absolute value. -format string c-like format string for output. -points Print points also. If points is chosen, the lift will be calculated for each set separatly. -pts same as -points. -n int Print Lift after each nth set (0 = print result at end). |

Example Input Data: | @title "Example will have centerpoint (0, 0)." -1 1.22465e-16 -0.5 0.866025 0.5 0.866025 1 0 & -1 1.22465e-16 -0.5 -0.866025 0.5 -0.866025 1 -2.44929e-16 |
