rndCauchy¶
Purpose¶
Computes Cauchy random numbers with a choice of underlying random number generator.
Format¶
-
r =
rndCauchy
(rows, cols, location, scale)¶ -
{ r, newstate } =
rndCauchy
(rows, cols, location, scale, state) Parameters: - rows (scalar) – number of rows of resulting matrix.
- cols (scalar) – number of columns of resulting matrix.
- location (scalar or matrix) – Cauchy location parameter, scalar or ExE conformable matrix with rows and cols
- scale (scalar or matrix) – Cauchy scale parameter, scalar or ExE conformable matrix with rows and cols
- state (scalar or opaque vector) –
Optional argument.
scalar case
state = starting seed value only. If -1, GAUSS computes the starting seed based on the system clock.opaque vector case
state = the state vector returned from a previous call to one of the
rnd
random number functions.
Returns: - r (rows x cols matrix) – Cauchy distributed random numbers.
- newstate (Opaque vector) – the updated state.
Remarks¶
The properties of the pseudo-random numbers in x are:
\[\begin{split}E(x) = \text{undefined} \\
Var(x) = \text{undefined} \\
Median(x) = \text{location}\end{split}\]
r and c will be truncated to integers if necessary.
