WebSal solves a linear system with 3 equations and 4 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form. Created by Sal Khan. ... we are augmenting with the linear "answers", and solving for the variables (in this case, x_1, x_2, x_3, x_4) when we get to row reduced echelon form (or rref). WebThe inputs to solve are a vector of equations, and a vector of variables to solve the equations for. sol = solve ( [eqn1, eqn2, eqn3], [x, y, z]); xSol = sol.x ySol = sol.y zSol = sol.z. xSol = 3 ySol = 1 zSol = -5. solve returns the solutions in a structure array. To access the solutions, index into the array.
