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;

Only the y values can be used for computation.
