How do I make an executable system solver?

I want to make an executable to import and solve the following system of equations from a text file using MATLAB:

[K]{u} = {F}

for example,

This is what I've tried:

u=cell2sym(textscan(fopen('arrDisp.txt'),'%s'))
F=cell2sym(textscan(fopen('arrForce.txt'),'%s'))
K=load arrStiffness.txt
s=solve(F==K*u)
st = structfun(@double, s, 'uniform', 0)
writetable(struct2table(st), 'sol.xlsx')

It does find the solution, but I cannot compile it because the vectors {F} and {u} contains symbols like u2 and u3.

So, is there any way to make it work?

Creation of symbolic expressions is not supported for use with MATLAB Compiler.
