Hi All,
I am trying to solve system of equations, as attached,
I have written a code, but my final matrix is 9*9 however, it should be 3*3….I understand i have 9 unknowns with 9 equations, but i wish to understand how could i solve it..
clearvars;clc; syms A11 A12 A13 A21 A22 A23 A31 A32 A33 real; eq1 = A11*-0.001179+A12*-6.581+A13*0.008718 == -0.5;eq2 = A12*-0.001179+A22*-6.581+A23*0.008718 == 0;eq3 = A31*-0.001179+A32*-6.581+A33*0.008718 == 0;eq4 = A11*-0.00251+A12*0.05848+A13*-0.039518 == 0;eq5 = A21*-0.00251+A22*0.05848+A23*-0.039518 == -0.5;eq6 = A31*-0.00251+A32*0.05848+A33*-0.039518 == 0;eq7 = A11*-0.0051200+A12*0.2779500+A13*0.0001469 == 0;eq8 = A21*-0.0051200+A22*0.2779500+A23*0.0001469 == 0;eq9 = A31*-0.0051200+A32*0.2779500+A33*0.0001469 == -0.5;[A] = equationsToMatrix([eq1, eq2, eq3, eq4, eq5, eq6, eq7, eq8, eq9], [A11, A12, A13, A21, A22,A23, A31, A32, A33]);
