We are using for-iterator loop, display is showing correct result but while analyzing graph we got to know it is having spikes.

We have having problem in implementation of for loop, the out of each element of for loop is having spike. Let's say that the output is to be retained at 49 but it's having spike.

As per my understanding the "assignment block" copies the input vector and update it in each step due to which these spikes occur. Use "MATLAB function block" instead of assignment block to assign the vector and remove the spikes.

Refer to the following code of the MATLAB function block:

function y = fcn(u, data, idx)
persistent temp
if isempty(temp)
    temp = u;
end
temp(idx) = data;
y = temp;
