Example #2: Write the following set of four
linear equations with 4 unknowns x1, x2, x3, and x4 in the matrix
form. Solve the equations using MATLAB.
0.1 x1+ 2.3 x2 + 3x3 + 4x4 =1
x1+ 3x2 -7x3 +5x4 =2
3x1+2x2+7x3 =3
x1 +2x2 +x3 +10x4=0
(b)Roots of Polynomials:
In order to obtain the roots of a polynomial with the
coefficients a1,a2,a3 ,... (where a1 is the coefficient of the
highest power, and so on in a descending order)...
