Simulink Coder -- Code generation Error for circshift command

Hello ,

In Simulink Model I have used circshift command . Code generation is successful but I am getting wrong generated code.

Please help me out.

function Value = fcn(u, Limit)

%#codegen

persistent queue

y = length(find(abs(u)>Limit));

% Set the parameters of our queue

n = 1; % length of each vector in queue

max_length = 6;

% Initialize a queue of length of n*max_length vectors

if isempty(queue)

queue = zeros(n, max_length);

end

queue_length = 0;

queue = circshift(queue, 1, 2); % Move each column to the right

queue(:,1) = y; % Add new vector to queue

queue_length = min(max_length, queue_length + 1);

Value = sum(queue);

This looks fine for me.What was the given input? What is the expected output of the Simulink model?What output are you getting from generated code?
