CAD2D

NAME

CAD2D - A Program for producing CADs of Rˆ2 Decomposition

SYNOPSIS

cad2d [-h|-v] [-noecho] [-t <num> ] [+N <numcells> ]

DESCRIPTION

The CAD2D program is a minor modification of QEPCAD for quantifier-free formulas in 2 variables. It is able to do some lifting steps completely with validated floating-point arithmetic, which can lead to much reduced overall time for 2-dimensional CAD computation. Particularly, if you’re interested in plotting a 2-dimensional CAD, this is a better choice than QEPCAD.

OPTIONS

	-h	Help information
	-v	Print version string
	-noecho	Turns off echoing of input

-t <num>

Sets a timeout of <num> seconds.

+N<numcells>

Sets garbage collected space to <numcells>. Default is 2000000. Maximum allowable is 1073741822 (Because "Word" is 32 bits).

+h

Prints Saclib help message.
