Simultaneous Equations Three Unknown

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...

Using an engine throttle valve modeling example, this demo shares some perspectives on creation of nonlinear models of dynamic systems from the measurements of its input and outputs. It describes useful workflows for approaching the task of data-based modeling using System Identification...

Morello Matrix Calculator is a simple, low cost utility for manipulating matrices of real numbers. It is as easy to use as a pocket calculator, but can perform most standard matrix operations for matrices up to 20 elements square. It also supports cut and paste operations allowing matrix data to...
