How to generate 3D Gaussian distribution with mean 0 covariance matrix I
Hi all, I need to generate data from a 3D Gaussian distribution with mean 0 and Covariance matrix I (identity matrix). I read from some statistic books but they only talk about sampling a 2D Gaussian distribution, for example using Box-Muller. The Box-Muller for 2D Gaussian can be described as " First con... 4 Apr 2010 13:43

Books on the zeta function?
Could anyone suggest a book that I could read to learn about the Riemann zeta function? I have done a lot of rigorous undergraduate coursework in mathematics (including real, complex, and functional analysis), and I want to eventually understand applications of number theory and the Riemann zeta function to mathema... 4 Apr 2010 11:31

3x10^10 cm/sec uniquely linked to the end of Finiteness at 10^40?? #563 Correcting Math
Let me backtrack. This is not working out as I thought. The disparity or skew is not the sole issue. Let me proceed through a different mechanism. I want the unique number of 3 x 10^10 cm/sec from using just the logarithmic spiral as purely time and the concentric circles as purely distance. I want to end... 3 Apr 2010 06:05

Problem with matlab auto rounding !!
hello professionals .. Im a beginner and need your help.. I have a matrix which contains numbers like 5*(10^9) and 6.5*(10^-5) , both in the same matrix.. when i enter the values, matlab rounds the small values of order (10^-5) to zero... i need the accurate numbers to work with & need to find the exact values..... 2 Apr 2010 20:24

speed of light found in purely mathematical numbers without any physical numbers #556 Correcting Math
Now in my prior post of #555, I had alot of assumptions to fetching the number 3 x 10^10 cm/sec for the speed of light from just purely the logarithmic spiral and the associated circles. Alot of assumptions that are reasonable in an Atom Totality. I assumed the speed of light is the largest speed possible a... 1 Apr 2010 16:53
