Returns a real matrix containing simulated samples of a uniform
random variable that has mean zero and variance one.
The integer scalars nr and nc
specify the number of rows and columns in the return value.
Suppose that f(x) is the density
function defined by
/ 1 / (2 b) if -b<x< +b f(x) = |
\ 0 otherwise where b is equal to the square root of 3.
It follows that the corresponding random variable is uniformly
distributed, has mean zero, and variance equal to
+b 3 2
/ 2 1 x |+bb
| f(x) xdx = --- - | = - = 1
/ 2 b 3 |-b 3
If you enter
O-Matrix will print four number with values between
plus and minus the square root of 3.
