The applications solvei) Simultaneous Equations X+Y=2; 2X+Y=2.5 andii) Differential Equation m(d^2x/dt^2)+b(dx/dt)+kx=F(t) with inputs m=2; b=0.7; k=1 and F(t)=0.5.The results... Platforms: Matlab

The "Level Horizon" command helps you, um, level the horizon in crooked photos. Simply open the photo, draw a straight line along a part of the image that should be perfectly horizontal, and run the command. The photo will be rotated so that the line is horizontal and the now crooked corners of... Platforms: Mac

Numerically solves systems of simultaneous nonlinear equations. It can fully explore defined intervals to search for multiple solutions or quickly find solutions starting with random seeds. You may predefine constants and specify the error bound for the results. Handles a wide variety of... Platforms: Windows
