FSOLVE inside for loop to change a parameter and save it

hi guys! i have this problem. i use fsolve to solve 3x3 non linear system and i want to change a parameter "ua" every iteration, and then i want to save the vector x and plot ua(n) vs x(n), any idea.

im using this code for example:

c lc

clear all

x0 = [-5; -5];        % Make a starting guess at the solution

options=optimset('Display','iter');   % Option to display output

k=100; 

for n=2:100; 

      ua(1)=1;

      ua(n)=ua(n-1)+0.1; 

[x,fval] = fsolve(@(x) myfun(x,ua(n-1)),x0,options)  % Call solver

end

the func file reads like this

function F = myfun(x,ua)

F = [ua*2*x(1) - x(2) - exp(-x(1));

        -x(1) + 2*x(2) - exp(-x(2))];
