Vary the Random number sampling time when it control over digital clock (built in Block) with different sampling time inside Embedded MATLAB function?

Question

My code is (inside embedded MATLAB function):

function y=example(t)
y=rand(1,1)*t;

t is digital clock input (simulation block) with sampling time (1/1e6). The y also generates a random number sequence (uniform distribution) in 1/1e6 sampling time. But I need the sampling time output y should be in (1/1e3) time.

How can I do it?

Answer 1

I'm going to assume that your input t is a vector of time points defined with the sampling time of 1e-6. As such, going from 1e-6 to 1e-3 is a factor of 1000. All you have to do is take your t vector and sample every 1000^th point. This will effectively create a digital clock input that has a sampling time of 1e-3 instead of 1e-6. In other words, all you have to do is this:

function y = example(t)
y = rand(1,1)*(t(1:1000:end));
