sensitivity analysis of data with multiple variables

I have a set of data that depends on 3 variables:

Sys_LCOE(jj,i,ii)
ii=1:1:length(YF);
i=1:1:length(PVprice);
jj=1:1:length(F_bank) ;
YF      =linspace(0.85,1.1,51);
PVprice =linspace(800,1600,51);
F_bank  =linspace(0,5,51);

(the N is put to 51 because file with N =101 was to big to paste here, N=101 would show the Sys_LCOE per percentage change in each variable within its range)

I want to analyze sensitivity of Sys_LCOE to a change in one variable at different values of other variables, if it is doable.

You can give me an example or post a link, or show how to do it with my data.

Thanks
