i have a two variable cost function to minimize,is there specefic type of optimization to do it , i am trying some metaheuristics and when introducing the second variable it shows "not enough input variables" any recommendations please ? thank you

for the algorithm used ive tried many metaheuristics and only worked with one variable ,is there a way to make any algorithm work with two variables or there are specefic algorithms for the task

%example
nvars = 23;
fun = @(xSv) costfunction(xSv(1:10), xSv(11:nvars));
[bestxSv, fval] = ga(fun, nvars);

There are several different minimizers possible. Everything except fzero() -- fzero() is restricted to one variable.
fun = @(XYZ) YourFunction(XYZ(1), XYZ(2), XYZ(3))
