Solve Equations in MATLAB

The following tutorials are an introduction to solving linear and nonlinear equations with MATLAB. The solution to linear equations is through matrix operations while sets of nonlinear equations require a solver to numerically find a solution.

Solve Nonlinear Equations with MATLAB

Source Code

 % Create new file myFunction.m
 function F=myFunction(z)
   x = z(1);
   y = z(2);

   F(1)=x^2+y^2-20;
   F(2)=y - x^2;
 end


 % Create new file mySolver.m
 clear all
 zGuess = [1; 1];
 z = fsolve(@myFunction, zGuess);
 disp(z)
