GCOMP(1)
NAME
gcomp - do computations on a graph file.
SYNOPSIS
gcomp [ -amilh ][ +variable value .. ][ file .. ]
DESCRIPTION
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.
EXAMPLE
- 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;
