Question

Matlab

Provide the MATLAB commands needed to determine the solution to the following system of equations in a MATLAB program (linearequation.m). Use MATLAB to check the solution by multiplying coefficient matrix A with the solution vector x, to produce b. That is, Ax = b. w + 3x + 4y = 31 2w + x + 3y + z = 27 9x + 7y + 2z = 72 4w + 3x + 2y + 2z = 27.

Answer 1

SOURCE CODE:

syms w;
syms x;
syms y;
syms z;
eqn1 = w+3*x+4*y==31;
eqn2 = 2*w+x+3*y+z==27;
eqn3 = 9*x+7*y+2*z==72;
eqn4=4*w+3*x+2*y+2*z==27;
[A,B] = equationsToMatrix([eqn1, eqn2, eqn3,eqn4], [w,x, y, z])
X = linsolve(A,B)

A*X
