MATLAB: Expressing a matrix with parameters and letters

matrixparameterssym

in my homework it is asked to solve B*b. The solution should however contain the three variables F1, F2 and F3 that are in b.

How can I write it? They just suggest to use the "sym" command…

Define the variables F1, F2, and F3 as symbolic variables.

syms F1, F2, F3
B = inv(A);
b = [0 F1 0 F2 0 F3 0 0 0 ]’;
x = B*b;

You want this solution?

C = cell(16);
k = 1:3;
C(k,2) = {'-B/H'};
C(k+4,2) = {'B/H'};
C'

G*m = d

G = [f1,f2;f3,f4];
d = [z1;z2];
m = G\d;
x = m(1);
y = m(2);
