ContinuousRandom

This block is a continuous random wave generator. Each output component takes piecewise constant random values. Each time an event is received on the block input activation port, the outputs take new independent random values. The output port size is given by the size of the parameter matrices. You can select the distribution.

Description

The ContinuousRandom block is a continuous random wave generator. Each output component takes piecewise constant random values. Every time an event is received on the input event port, the outputs take new independent random values. Output port size is given by the size of the parameters matrices. You can choose the distribution.

Supported distributions are: Uniform, Normal, Lognormal, Beta, Gamma, Chi-squared, Exponential, F, T, Pearson I, Pearson III, Pearson V, Pearson VII, Inverse Gamma, Inverse Beta.
