hi all
i just wanna ask,how we do the increasing value by changing manual switch in simulink??
for example: i have manual switch, with 2 constant block connect to it, first signal= 1 , second=0. i have calculation that everytime we change value in manual switch the system will add 10 to the current signal.
how we do it with embedded matlab function??

Do you have to use EML? If not, it could be done easily in Simulink using a trigger subsystem. Type "sldemo_counters" to open the demo model, connect your manual switch block output to the triggered subsystem. Inside the system, change the trigger from "risgin" to "either", change the constant from 1 to 10 then you got it.

Please do not open duplicate questions; it just ends up duplicating efforts.
You can edit your previous question if needed.

FWIW, here's an EML implementation:
function y = mycounter(u)
%#eml
persistent count;
persistent prevInput;
firstInput = false;
if isempty(count)
count = 0;
end
if isempty(prevInput)
prevInput = 0;
firstInput = true;
end
if ~firstInput
if (prevInput ~= u)
count=count+1;
end
end
prevInput = u;
y = count;
end

Okay, feed the switch output signal to the triggered subsystem, still choose "either". Also, feed the switch output signal to an Inport of the the triggered subsystem, multiple it by 10, then feed it to an Integrator block. Did not verify. Should work. Try it yourself.

If 1 then current value is increased by 10. Increased only once, or every time step as long as the switch output is 1?
