Number of variables (NVARS) must be a positive integer.
Error in GAONN (line 53)

I did not read your code in detail, but the line where you call ga is
[x, err_ga] = ga(h, c, ga_opts);
Look at the documentation for the correct syntax of ga:
x = ga(fun,nvars,A,b,Aeq,beq,lb,ub,nonlcon,options)
Use [] for inputs that you do not use. You need to include nvars as a positive integer.
