How can I store dynamically a vector in a For iterator Simulink Subsystem?

I have this simple system: The code in the function is: function a = fcn(iteration,a) a(1,iteration) = iteration; end The outside Simulink layer is the following (a is initialized as a = zeros(1,5)): The loop is: for i = 1:5 and I want to store…

Is it possible to build a (1/a*s+b) subsystem block with individual blocks in simulink?

I'm trying to build a subsystem in simulink with 3 inputs and those would be 2 constants (a and b coefficients) and the input signal (a step, for example). And inside the block it should work as a transfer function (1/as+b). I've tried somethings…
