NOTE: Chi-Square Distribution.....IHAVE TO DO THIS IN MATLAB!!! WHERE ARE MY MATLAB GENIUSES OUT THERE?!?!

Use N(0,1), N(1,4), N(5/9) and N(-5,16) to generate Chi-square distribution (degree of freedom :4). Following is an example of Chi-square pdf with the sigma has different value of 2 and the mean values vary from 0 to 4.

x = 0:0.2:15;
