This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust.It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy + cy^2 + dx + ey + f = 0,i.e. it returns the vector...

solvesimul.m can be easily adapted to solve more equations but as it stands it will solve 2 unknowns in 2 equations (1 non-linear and one linear).To solve equations of this form... a*x + b*y = A (1) a1*x^2 + b1*y^2 = B (2)...with fsolve (used by solvesimul.m) you need to rewrite them so that they...

This function solves the linear fractional-order differential equations (FODE) with constant coefficients. The short memory principle has not neen used here, so the length of input signal is limited to few hundred samples. The parameters of the FODE (in its standard form) are the inputs of this...
