Hey everyone. I am trying to solve an equation for a physics problem where we

[K][d] = [F].

[d] = [0;
    A1;
    Y2;
    A2;
    Y3;
    A3;
    0;
    A4];

[F] = [V1;
    M1;
    0;
    3600;
    -500;
    0;
    V4;
    0];

and K =

  1.0e+06 *
    [0.2633    0.1317   -0.2633    0.1317         0         0         0         0
    0.1317    3.1600   -0.1317    1.5800         0         0         0         0
   -0.2633   -0.1317    0.3871   -0.0698   -0.1237    0.0619         0         0
    0.1317    1.5800   -0.0698    4.1500   -0.0619    0.4950         0         0
         0         0   -0.0052   -0.0619    0.0103         0   -0.0052    0.0619
         0         0    0.0619    0.4950         0    1.9800   -0.0619    0.4950
         0         0         0         0   -0.0052   -0.0619    0.0052   -0.0619
         0         0         0         0    0.0619    0.4950   -0.0619    0.9900]

Is there any know commands to solve this equation for me? I declared all the symbols as syms at the start of code. I'm having trouble and any insight is appreciated! Thank you!
