[Scilab-users] How to use champ

[shahriqeen]

Thanks for the solution of the system1
for system1 we use fchamp
How  about the system 2 below, we need to use fchamp or champ?

funcprot(0)
function System2()
    
    clc;
  
    t=0:2:100; 
    y=0:2:100; 
    
// initial value
    t(1)=0; 
    y(1)=0;// g(x)     
    y1(1)=0.4; // for x 
    y2(1)=0.4; // for y 

// Varible value
    A=2.0;B=1.0;C=1.0;D=0.2;W=0.2;P=(1-exp(-1.2*2))/1.2;  
     
    n=length(t);
    
    cnt=0;
    
    for i = 1:n-1
        
        y(i+1)=1/(C+y1(i))

        y1(i+1)
=y1(i)*(1+(P*B*W))/(1-(B*P)+(B*P*W)+(B*P*y1(i))+(A*P*y(i+1)*y2(i)))//value
for x
        y2(i+1) = y2(i)*(1+(P*y1(i)*y(i+1))-(D*P*W))/(1+P*D+D*P*W)//value
for y
                  
        cnt = cnt + 1;
    end
  
    plot2d(y1,y2,1);
    xlabel('x');
    ylabel ('y');  
endfunction
