Measuring memory used by a program?
I have a Java program. I want to measure the total memory used by the program, especially the peak memory. Is there a way to do it?
I have tried utilities like time (which returns 0) and top (which is not very useful) as the program does not run for long.
Can anyone suggest a way to do this?
Thanks,
Santhosh Pathical

FITYK(1) General Commands Manual FITYK(1)
NAME
fityk - non-linear curve fitting and data analysis
SYNOPSIS
fityk [OPTION]... [FILE]...
cfityk [OPTION]... [FILE]...
DESCRIPTION
This manpage documents briefly the fityk and cfityk programs for nonlinear fitting of analytical functions (especially peak-shaped) to data
(usually experimental data). In other words, for nonlinear peak separation and analysis.
It was developed for analyzing diffraction patterns, but can be also used in other fields, since concepts and operations specific for crys-
tallography are separated from the rest of the program.
Fityk offers various nonlinear fitting methods, subtracting background, calibrating data, easy placement of peaks and changing peak parame-
ters, automation of common tasks with scripts, and much more. The main advantage of the program is a flexibility - parameters of peaks can
be arbitrarily binded with each other, eg. width of peak can be an independent variable, can be the same as width of other peak or can be
given by complicated - common for all peaks - formula.
The program comes in two versions: fityk , the GUI version and cfityk , the command line version.
A user manual for fityk and cfityk can be found in /usr/share/doc/fityk/html/fityk-manual.html.
