Hi, I have a code where it is a sin wave for first 0.6 seconds and 0 for the next 0.4 seconds. Which i have created using if statements etc. so its a matlab file. Now thing is i want to generate this as a voltage supply, how do i import this matlab file into the voltage supply. I know there is a 'from workspace' and 'from file' function. but i have no idea how to use this. thanks.

And here comes the debug problems :).

so what you need to do is :

I already answered you in your previous post, it's a best practice to do it directly with Simulink blocks.

But if you insist to use directly an external mfile, you need to use another block : interpreted matlab function

so : interpreted matlab function

And best practice, because calling external files often creates some debugging problems.

also does that matlab file have to be a function or a file? And also do i have to specify the time during which it ran in that function? What do i put into the integrated maths function aargh i am so confused? can u show me how to do it?

heres my code

t = 0:0.05:1; %#ok<*NBRAK> a = size(t);

y = zeros(1,a);

i=1; for t = 0:0.05:1

if t<0.6

y(i) = sin(t);

elseif t >= 0.6

y(i)=0;

end

i = i+1;

end

much appreciated

OK with ps-s converter i have got theres a circle on end, and an arrow on another. the circle doesn't seem to connect to anything….the arrow does….., so i just connect the arrow to the voltage supply, and then ground that the voltage supply, as i can't connect when its in a closed circuit, as it is closed….
