I am writing two function, one to solve a system of nonlinear equations using jacobi's method, and one to find the most efficient relaxation it. My problem is that I want to pass two values from the first code (jacobi) to the second code (plotter), But I can only figure out how to send on. I would really appreciate any help. Here is the first pare of my Jacobi code (requires 4 input) and my plotter code:

function [bad,count]=jacobi(x1,x2,x3,w)

re=10^(-3); %Relative Error Tolerance

rt=10^(-3); %Risidual Tolerance

maxi=400; %Maximum Iteration

count=1; rele=re+1; res=rt+1; %Counter , reletive error, and residual

bad=0; %Boolean to pass to the plotter if it diverges

%%%%%%%%A bunch of code that I don't really think matters for this is here%%%%%%%%%

if rele >= 100 %Breaks loop if the values are diverging

disp('The relaxation is bad, try again');

count = 400;

bad=1;

break

end

function plotter(x1,x2,x3)

k=1;

for(w=0.01:0.002:0.6)

count=jacobi(x1,x2,x3,w);

curveJ(k,2)=count; %number of iterations required

curveJ(k,1)=w; %relaxation factor

k=k+1;

bad=jacobi(bad);

if(bad==1)

break

end

end
