How to get values out of a matrix equation, when one of its elements is an array?

Hello everyone,
My question is how can I solve a matrix equation, when one of its elements is an array?
This error comes up in the command window preventing 'q' to be found. "Dimensions of arrays being concatenated are not consistent."
% Stating variables
omega = 100
M_22 = (0:0.1:20);
C_22 = (0:0.2:40);
F_1 = (0:0.4:80);
% Creating Matrix
M = [1 0; 0 M_22];
C = [1 2; -2 C_22];
K = [100 0; 0 100];
F = [F_1; F_2];
% Equations
Z = -(omega^2)*M + omega*j*C + K;
Z_inverse = inv(Z);
q = Z_inverse*F;
Thanks in advance!

tvals = 0:0.1:20;
numt = length(tvals);
v3 = zeros(2, numt);
for tidx = 1 : numt
t = tvals(tidx);
....
v3(:, tidx) = q;
end
