why MATLAB hang while inverting that matrix, I left it more than a day willing to get any result, but nothing happened
K_total\[0;0;0;0;0;0;0;0;0;0;1;0;0;0;0;0;0;0;0;0;0];
Thanks

Your K_total is symbolic so you are asking for a symbolic solution rather than a numeric solution.

You may think that a symbolic result with only 21 unknowns cannot be too big, but it will be IMMENSE.

I cannot read the .mat file as I do not have the symbolic toolbox, so I do not know how complex it is.
But remember that even just the exact solutions of a quartic is very big.
