Hi ! guys,

Somebody could tell me how to wite a matlab(or simulink) Laplace transform eq.

(1-exp(-st))/s...........

Thank you for your help!
 

Try This Code:


syms s t y
y=laplace((1-exp(-s*t))/s);
ezplot(y)

I tried it and it worked nicely also if you can please PM me if the output was what you anticipated or not
 

Hi
can anyone help me out with simulink ?

i need an ALAMOUTI SPACE TIME BLOCK in SIMULINK

or can any one tell me how to make a user defined code block in simulink

thanx i need help urgently

tc
 

But the "S" in the equation (1-exp(-S*td))/S is already a laplace transform symbol(just like laplace(u(t))=1/S ). Where td is a constant.

But I will thank you any way.

Click to expand...

Then Either use the same code and change the function laplace to ilaplace to get the inverse laplace transform and draw the signal in the time domain

or perform the laplace function over the original signal in the time domain and ezplot the result

;)
