my function is simple 3 variables as shown bellow

function x = material(s,f,d)

x = (-0.552042 - (6.39734e-005*(s)) + (14.3154 (f)) + (0.261111 (d))); end and while running GA i get "not enough input arguments" This is the first time iam using GA tool so any one please help me with this problem. And specify any other steps that has to done in GA optimization tool.

在 MATLAB Online 中打开

function [s_star,f_star,d_star]=find_optim()
   nvars=3; %s, f, d
   options=gaoptimset(@ga);  % defaults, but you will need to change things
   options=gaoptimset(options,'PlotFcns',{@gaplotbestf,@gaplotbestindiv});
   x_star=ga(@material,nvars,options); 
   s_star=x_star(1); f_star=x_star(2); d_star=x_star(3); 
end
function x = material(x)
   s=x(1); f=x(2); d=x(3);
   x = (-0.552042 - (6.39734e-005*s) + (14.3154*f) + (0.261111*d));
end
