Hi dear
I follow your steps but the matlab gave me this message
Warning: The model 'untitled' does not have continuous states, hence Simulink is using the solver 'VariableStepDiscrete' instead of solver 'ode45'. You can disable this diagnostic by explicitly specifying a discrete solver in the solver tab of the Configuration Parameters dialog, or by setting the 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics tab of the Configuration Parameters dialog Warning: The model 'untitled' does not have continuous states, hence Simulink is using the solver 'VariableStepDiscrete' instead of solver 'ode45'.

Find the Configuration Parameters dialog and make the suggested adjustments. (It may continue to make suggestions until it is happy with your settings.)
Simulation->Model Configuration Parameters->Solver->Solver: Discrete

this is the matlab code i want to plot it in scope
please help me to solve this problem
fs=20E9;%sample rate-10 times the highest frequency
ts=1/fs;%sample period
t=[(-4E-9-ts):ts:(4E-9-ts)];%vector with sample instants
t1=.5E-9;%pulse width(0.5 nanoseconds)
x=(t/t1).*(t/t1);%x=(t^2/t1^2)(square of (t/t1)
A=1;%positive value gives negative going monopulse;neg value gives %positive going monopulse
y=A*(t/t1).*exp(-x);%first derivative of Gaussian pulse function
plot(t,y)

So use
[t',y']
in your "from workspace" block.
And change the simulation run time (next to the play block) to be your tmax (3.9500e-09).
You also have a to solve the problem where you have negative time. Since simulink doesn't do negative time. Perhaps add an offset?

dears it's still the same problem no plot display in scope

I need some help in other problem please
How i can generonate pulse one between 19 and 20 then zeros until 29-30 pulse one after that the pulse repeat 0001,0001,0001.............. Also, I want to show it on scop
