PROBLEM 1
Tthe random variable Z is given as Z= X + jY where X,and Y are zero mean independent and identically distibuted gaussian random variables. Write matlab code
a- To plot simulated and theoritical probability density fucti**
PDF and show that they are in good agreement
b- To plot the simulated and theoritical cummulativd distibuti** functi** CDF and show that they are in good agreement.

problem 2
write a matlab code to generate N samples according to Gaussian distibuti** with mean m and variance sigma square [those should all be inputs to the program] perform the following estimates:
1- the mean
2- the variance assuming the mean is known
3- the vaiance assuming the mean is unknown
