Absolute Value Equations

Simulation of Absolute-Value Output Circuit is carried out with operational amplifier,diodes and other components available in Simscape 2.1 version. Regardless of the polarity of the input signal, the output of the circuit is always positive going and this is displayed in the scopes.

Scalar::Properties is a Perl module package that contains run-time properties on scalar variables. SYNOPSIS use Scalar::Properties; my $val = 0->true; if ($val && $val == 0) { print "yup, its true alright...n"; } my @text = ( hello world->greeting(1), forget it, hi...

Libeval provides simple means of evaluating simple arithmetic expressions involving literal numeric values, variables and functions using the addition (+), subtraction (-), multiplication (*), division (/), modulo division (), exponentiation (^), sign (+-), percentag (%) and grouping (())...

In most languages with closures, it is possible to change a closed-over value and have the change visible in other closures which share a reference to the same variable. Python's syntax makes this impossible. Putting your changeable values inside a mutable object like a list-- it may occasionally...
