Gaussian distribution for 2D points

I want to generate well distributed 100 points using gaussian distribution in a 100x100 region having seperate variances in x-axis and y-axis () (something similar to attachment). I have tried the following code, however, all the points are clustered around (50,50). Any help will be appreciated. TIA

m = 50;	  %Mean
v = 30;	  %Variance
d = 300;      %Length
z = m + sqrt(v)*randn(d,2);

Where is X coordinate?

If you increase the value of v (the variance), you will get more widely dispersed points.
