problem in key generation ( chaotic 3D)

hi friends .... how are you.

I have problem when key generation ( chaotic 3D) and store results in 3 arrays 1*3888801 , but all values in cells are (NAN) , why ?

the code :

 function [Rk1,Gk2,Bk3] = FUC_keis_R_G_B(Rk1,Gk2,Bk3,sizeimage)

% control parameters
a(1) = 35; b(1) = 1.3; c(1) = 3; d(1) = 8; e(1) = 10; f(1) = 2; g(1) = 5 ;  h(1) = 0.5 ;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
for n=1:sizeimage
    Rk1(n+1)=a*(Gk2(n)-Rk1(n))+b*Gk2(n)*Bk3(n);
    Gk2(n+1)=-c*Rk1(n)*Bk3(n)+d*Gk2(n)+e*Rk1(n);
    Bk3(n+1)=f*Rk1(n)*Gk2(n)-g*Bk3(n)+h*Rk1(n); 
  
end

also , I want code used above keis with encryption (r , g,b) image colore

Could you give us some sample input?

Also please show

nnz(~isfinite(Rk1))
nnz(~isfinite(Gk2))
nnz(~isfinite(Gk3))

Rk1(1)=0.5684;
Gk2(1)=0.4284;
Bk3(1)=0.2680;
%%%%%%%%%%%%%%%%%%
[rows,columns ,numberOfColorBands]=size(rgbImage); % %%%%  540x720 uint8

This does not answer my questions about sample input or the number of non-finite values in the variables.
