This is the command gcomp that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
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
