Gaussian function power spectrum (Matlab)
The problem is your calculation of the theoretical Fourier values.
When you do a DFT with N points, the interval between points on the frequency axis is \$ \Delta f = 1/(N t_s) \$ where \$ t_s\$ den …

Gaussian Function Fourier Transform (Matlab)
The FFT looks flat, because the value of your a is too high.
Secondly, you should use a different x-axis for the FFT plot. With N+1 time values, you get FFT points for nu values from -N/2 to +N/2.
