A site visitor wants to sign up for a N-day series of emails. In a block, he enters his email address, select a preferable set of emails and clicks submit. Any emails in the system set to 'Day 0' are immediately sent. Each day thereafter, a cron job triggers the sending of emails appropriate for...

This script contains a function that finds out the gcd(a,b)(great common divisor of a and b) as a linear conbination of a anb b, ax by=gcd(a,b).

This is an instructional GUI to be used for learning how Euler angles, DCMs, quaternions, and Euler vector parameters relate in the rotation of cartesian frames (A to B). Can also be used to convert between all 4 values, however see below for a function that accomplishes this.Features:- All 12...
