Embedded Matlab Function - Output for every calculation
显示 更早的评论
Good day to all!
I have some simple code:
function Pr = fcn(unused)
%#eml
k = 100;
Pr = 180;
for i = 1:k
x = Pr * 0.05;
y = Pr - x;
Pr = y;
Pr;
if (Pr == 0 || Pr < 0)
Pr = 180;
end
end
Intention here is simple: Decrease the value of Pr until equal to or less than zero and reset. Concurrently, see the rise and fall of the same on scope. But all i get is a single constant output(as shown in the pic).
WHERE AM I GOING WRONG?
Please let me know!

Hi,
I think there is a misunderstanding of how this works. The MATLAB code you write is executed at each time step, completely. Since it does not depend on the input, it will give the same result each time (i.e. in each time step) where it is called ...
You could do the following:
- add a unit delay block to your model
- feed the output of your EML block to the input of the unit delay and from the unit delay to the EML block
- remove the loop "for i=1:k" from your MATLAB code
