I wish to continously reuse the outputs generated from a previous function as inputs to subsequent functions. My aim is to produce a chained function ouput. What is the best or most effecient way to generate an overal output 'y_0_n' as seen below from an chained functional output in MATLAB.

x_0 = [1:10];
x_1 = Varx_1*func1(x_0);
x_2 = Varx_2*func1(x_1);
x_3 = Varx_3*func1(x_2);
% ................
x_n = Varx_n_1*func1(x_n_1);
y_0_n = Vary_n_1*func2([x_0;x_1;x_2;x_3;x_4;....x_n-1])

Two function actually, functions 1 generates linked concated outputs for fuction 2.

You may proceed something like this:

x0 = 1:10 ; 
n = 10 ;   % number of times the function func1 to be called 
var = rand(n,1) ;   % your variables. I assume n and length of var is same as you have shown 
m =  value ;        % length ofoutput of func1  
X = zeros(n+1,m) ;    % where m is output length of func1
X(1,:) = x0 ; 
for i = 2:n+1
X(i,:) = var(i-1)*func1(X(i-1,:)) ; 
end
y = vary*func2(X) ;
