MotionGenesis™ Basics
To invoke the program (after the program has been installed):
• Double-click on MotionGenesisStartHere
• Or, from the operating system prompt, type MotionGenesis
On line (1), type sum = 2 + 2
Press Enter to see the response -> sum = 4.
Enter an expression to see automatic simplification.
fun = 3*sin(t)^2 + 2*cos(t)^2 -> fun = 2 + sin(t)^2
Differentiate with respect to time by typing.
good = Dt(fun) -> good = 2 + sin(t)^2
To solve a linear algebraic equation for x, type:
Variable x Solve( 2*x - 8*t = 6, x ) -> x = 3 + 4*t
To solve a nonlinear algebraic equation with a guess for x, type:
Solve( x^2 = cos(x), x = 0.1 ) -> x = 0.8241323
To solve the 2nd-order ODE (ordinary differential equation) y'' = -sin(y) with initial values y(0) = 1 m and y'(0) = 0 m/s and write the results to the data file MGDemo.1, type:
Variable y'' = -sin(y) Input y = 1 m, y' = 0 m/s Output t seconds, y meters ODE() MGDemo
To plot data in MGDemo.1, with the 1st column as the x-axis and the 2nd column as the y-axis, type
Plot MGDemo.1[1,2]
Alternatively, to have MotionGenesis™ write the file MGDemo.m so MATLAB® can solve the ODE and create the plot, type:
Variable y'' = -sin(y) Input y = 1 m, y' = 0 m/s OutputPlot t seconds, y meters ODE() MGDemo.m
To save your commands to the file MGDemo.txt, and exit the program type:
Save MGDemo.txt Quit
To edit MGDemo.txt, use a text-editor.  For example, edit the file MGDemo.txt by putting the following comment line at the top of the file (and save the file):
% MotionGenesis: MGDemo.txt
To run the modified MotionGenesis file MGDemo.txt, re-start MotionGenesis, and type run MGDemo.txt.
To save your commands together with output responses, type: Save MGDemo.html.  To subsequently view that file, go to your computer's MotionGenesis folder and double-click on the file MGDemo.html.
Online help
For general help and/or a list of commands, type Help
