Question

Use matlab backslash operator to output the solution of system of equation.

Print the unknowns in console.

Equations are

7*a+12*b+10*u=11,

3*a+4*b+19*u=10,

14*a+3*b+12*u=17,

Answer 1

Code:

clc

clc
clear

syms a b u
eqns = [7*a + 12*b + 10*u == 11,
        3*a + 4*b + 19*u == 10,
        14*a + 3*b + 12*u == 17];
[A,b] = equationsToMatrix(eqns);
%a) using '\' 
unknowns = A\b;
a = unknowns(1)
b = unknowns(2)
u = unknowns(3)

Output:
