Hi all,

I am fresh to use matlab, so I want to know if I can use Simulink to generate signal for me to test my analysis tools programmed by matlab recently.

Because it is quite time consuming for me to make a demanding signal with matlab...

In this mean time of COVID-19 caused home-office situation, no instruments (e.g. function generator or real experiment) besides me so I'm considering maybe Simulink can do a little bit replacement of them.

What type of signal do you want to make in Simulink? Is it described by a mathematical formula, differential equations?

Hi Ameer good to see you,

For example, basic sine wave, pulse or maybe amiplitude varying sine waves and pulses

在 MATLAB Online 中打开

sim_model.mdl

The attached file (saved in R2020a) shows how to generate different types of signals in Simulink and export them to MATLAB's workspace. It uses 'To Workspace' blocks to send data from Simulink to MATLAB. You can plot these signals in MATLAB by using the 'out' struct given by the Simulink. For example,

plot(out.varAmpFreqSine)

Thanks!

To conclude, what I to have do is to use Simulink to generate signal, export it to the Matlab workspace and test my algorithm such as max value detection that you answered to me last time, am I right?
