Hi Samhy,
So you want to generate square pulses using 'Simulink MATLAB function' block and in order to do so, we need to configure the Inputs and Outputs of the model.
- Define the inputs and outputs of the function, let say 't', 'period', 'amplitude' are inputs and 'y' is the output.
- Use 'Constant' block for period and amplitude and 'clock' block to provide the current simulation time t.
- To visualize the output, use the 'scope' block.
Attaching the link to demo model, make necessary changes according to the requirement.
MATLAB code that generates square pulses (Needs to be defined inside the ‘MATLAB function’ block) :
function y = fcn(u, data, data1)
time_in_period = mod(u, data);
if time_in_period < (data / 2)
y = data1;
else
y = 0;
end
The below screenshot is the output of the model:
I hope this was helpful.
