How to plot Amplitude Spectrum of CT and DT System Response

Hi,

I want to plot this function in MatLab, but it either doesn't plot (session just crashes after a few minutes), or it says that imaginay/complex numbers can't be plotted.

Can anyone help me with the syntax/commands for these functions?

I'm fairly new to matlab so I don't know how to plot this. Here are the pictures of 2 functions (CT and DT):

REFERENCE/EXAMPLE:

The plots are supposed to look like this:

Hi Wali,

I understand that you want to plot the amplitude of the continuous-time frequency response and discrete-time frequency response . This can be done in MATLAB using the abs function as,

figure
plot(w,abs(Y_jw)) % Continuous-time Frequency Response 
figure
plot(v,abs(Y_ejv)) % Discrete-time Frequency Response

It is not possible to plot complex numbers by directly providing them as arguments in the plot function as of now.
