gcomp - do computations on a graph file. |

gcomp [ -amilh ][ +variable value .. ][
file .. ] |

Gcomp reads each graph file in sequence and
computes the specified calculations. The type options are as
follows: |

-n Print the name of each curve. |

-a Print average and standard deviation of each
curve. |

-m Print minimum and maximum for each
curve. |

-i Print Romberg's approximation to the integral of
each curve. |

-l Print the slope, intercept, and correlation
coefficient using the least squares method of linear
regression. |

-h Do not print a header in the output. |

The calculations will be displayed as columns in the order they are specified on the command line. If no files are given, the standard input is read. |

Variables can be set explicitly with +variable value
options. The only truely useful variables for this program
are xmin and xmax. They determine boundaries for the
calculations. |

To compute the approximate integral of sin(x)/log(x) from 2 to 4: |

gcomp -i A(x)=sin(x)/log(x); Anpoints=100; xmin=2; xmax=4; ^D |

Only the y values can be used for computation. |
