Hi I have 8 equations with 8 unknowns as shown below.
p1(1) = alpha1 * ([g11 g12 g13] * p_1);
p1(2) = alpha1* ([g21 g22 g23]* p_1);
p2(1) = alpha2 * ([g11 g12 g13]* p_2);
p2(2) = alpha2 * ([g21 g22 g23]* p_2);
p3(1) = alpha3 * ([g11 g12 g13]* p_3);
p3(2) = alpha3 * ([g21 g22 g23]* p_3);
p4(1) = alpha4 *([g11 g12 g13] * p_4);
p4(2) = alpha4 *([g21 g22 g23] * p_4);
I know the values of the 3x1 vectors p1,p2,p3,p4, p_1,p_2,p_3,p_4...
g11, g12.. till g32 are my unknowns that I want to solve. alpha1, alpha2,alpha3 and alpha4 are also equations with the variables of g32 and g31 as shown below
alpha1 = 1 / ([g31 g32 1]*p_1);
alpha2 = 1 / ([g31 g32 1]* p_2);
alpha3 = 1 / ([g31 g32 1]* p_3);
alpha4 = 1 / ([g31 g32 1]* p_4);
I have used
syms g11 g12 g13 g21 g22 g23 g31 g32;
to declare the symbols.. when I solve these equations using the "solve" command, the "ans" matrix just says [g11; g12; ..; g32] instead of numericals values of the solved equations.. how do I get the values?

If both sides of equation having unknown values for variables, How do you get the values?

If both sides(i.e LHS, RHS) of equation having unknown values for variables, How will you get the values?
