My code is like that and MATLAB gives me error of inconsistancy, how can i solve overdetermined linear system?
syms e0 e1 e2
T1=1;
T2=3;
T3=4;
T4=5;
T5=6;
TM1=8;
TM2=7;
TM3=6;
TM4=5;
TM5=4;
Eqns = [e0 + T1*TM1*e1 - T1*e2 == TM1
e0 + T2*TM2*e1 - T2*e2 == TM2
e0 + T3*TM3*e1 - T3*e2 == TM3
e0 + T4*TM4*e1 - T4*e2 == TM4
e0 + T5*TM5*e1 - T5*e2 == TM5];
[A,b] = equationsToMatrix(Eqns, [e0, e1, e2]);
x=linsolve(A,b);
x
OUTPUT:
Warning: Solution does not exist because the system is inconsistent.
x =
