Welcome to Civilized Software's New Home Page (WWW.CIVILIZED.COM)


We are the developers of MLAB, an advanced mathematical and statistical modeling system.

MLAB is an ideal tool for mathematical and statistical exploration, and for solving simulation and modeling problems such as chemical kinetics, pharmacological compartmental models, multiple site ligand binding, neurophysiological modeling, and ultracentrifuge models, to name just a few. MLAB is especially designed to handle differential equation models.

There are versions of MLAB for PC (DOS, Windows3.1, Windows95/98/NT/2000/XP/Vista/Win7/Win8/Win10/Win11, Linux - both 32 and 64 bit systems where applicable), Macintosh (PPC OS 8.x, OS 9, OS X-classic mode(emulation)), and OS X-native mode for both Intel-Macs and PPC-Macs, older Motorola Macintosh systems, SGI, and NeXT (Motorola, Intel, and HP) platforms. (There is not a version of MLAB for newer OS-X 10.10 and later non-Intel Macs.)

Data Analysis and Modeling Services are also available! Contact: [email protected]

"Much of the joy of science is the joy of solid work done by skilled workmen. ... There is a great satisfaction in building good tools for other people to use. ... The essential factor which keeps the scientific enterprise healthy is a shared respect for quality. Everybody can take pride in quality, and we expect rough treatment from our colleagues when we produce something shoddy." - Freeman Dyson, Disturbing the Universe.

Descriptive material plus a collection of technical reports showing the application of MLAB are available. Please take a look at whatever you wish from the selections offered below. Especially note the Technical Application Notes and Examples!
