Generate uniformly distributed random numbers.

Description
The Uniform Random Number block generates uniformly distributed random numbers over a specifiable interval with a specifiable starting seed. The seed is reset each time a simulation starts. The generated sequence is repeatable and can be produced by any Uniform Random Number block with the same seed and parameters. To generate a vector of random numbers, specify the Initial seed parameter as a vector.
To generate normally distributed random numbers, use the Random Number block, described on Random Number.
Avoid integrating a random signal because solvers are meant to integrate relatively smooth signals. Instead, use the Band-Limited White Noise block.
Data Type Support
A Uniform Random Number block outputs a real signal of type double.
