Answer to Question #295978 in MatLAB for Ankit Kotia

Question

Solve the following system of six linear equations on MatLAB:

2a-4b+5c-3.5d +1.8 e + 4 f= 52.52 

-1.5 a + 3b +4c-d-2e +5f= -21.1 

5a+b-6c+3d -2e +2 f = -27.6 

1.2a 2b +3c+4d-e+4f=9.16 

4a+b-2c-3d-4e+1.5 f= - 17.9 

3a+b-c+4d-2e-4 f= -16.2

Answer 1

A = [2 -4  5 -3.5 1.8   4
  -1.5  3  4   -1  -2   5
     5  1 -6    3  -2   2
   1.2  2  3    4  -1   4
     4  1 -2   -3  -4 1.5
     3  1 -1    4  -2  -4];
b = [52.52; -21.1; -27.6; 9.16; -17.9; -16.2];
x = A\b

Results:

x =

 -201.6990

 -348.1180

 -31.3556

 117.8174

 -334.8739

  58.8395
