Create a continous stepwise increase in Simulink

Hi!

Is there any way to create a stepwise increase in Simulink using parameters (a,b,c) which can be chosen from a MATLAB script. I have tried using the step function which does not work, and the signal builder which is not good as i would to change parameters from my MATLAB script. What i want is the following variable f(t) to do the following determined by the parameters a,b and c.

Any help is appriciated.

You can use the MATLAB function block and a clock to create this signal as shown in the image

The code inside the MATLAB function block is

function y = fcn(t)

a = 5;
b = 2;
c = 3;

t = t - a;
y = 0;
if t > 0
    y = ceil(t/c)*b;
end
