Question

Can I please have help with the following Scilab

5. Use Scilab to create following rational expression matrix: 1+x 1 +2x - x2 x 1+x1+x 1-X 1+x+3x3 5x +x3 217 1 2x 1- 1 +3x +x2 1-x +x2

Answer 1

Answer

x = poly(0,'x');                   //seed for defining polynomials with symbol x
simp_mode(%f);                       //turn off the simplification mode

r11 = (1 + x) / (1 - x^2);           //first element of first row
r12 = (1 + 2*x -x^2) / (1 + x);       //second element of first row
r13 = x / (1 + x^2);               //third element of first row

r21 = 1 + x + 3*x^3;               //first element of second row
r22 = (3 - x) / (2 + x^2);           //second element of second row
r23 = 5*x + x^3;                   //third element of second row

r31 = (1 + 2*x) / x;                   //first element of third row
r32 = (1 - x^3) /(1 + 3*x +x^2);       //second element of third row
r33 = 6 / (1 - x + x^2);               //third element of third row

m = [r11,r12,r13;r21,r22,r23;r31,r32,r33]   //create the 3x3 matrix
