Simultaneous Equations Solver

This script allows you to run a linear equations solver using eval and built-in complex numbers.One could add one more line to insert '*' where needed, i.e. "100x" -> "100*x", add some input validation, in particular check whether the equation is actually linear and not quadratic or cubic, and...

Simple program that makes it faster and easier to solve simultaneous equations using the solve command.

This customised function solves one type of non-linear systemof 3 simultaneous equations in 3 unknowns: k, L and r0 in 3 equations with 4 knowns: zeta, eeta, d and angle.function matrixresults = symsolvenonlineq(n,degrees,dinput)% EXAMPLE USAGE: m=symsolvenonlineq(3,45,20)% nb: takes around 738s...

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...
