rndLaplace¶
Purpose¶
Computes Laplacian pseudo-random numbers with the choice of underlying random number generator.
Format¶
-
x =
rndLaplace
(r, c, loc, scale)¶ -
{ x, newstate } =
rndLaplace
(r, c, loc, scale, state) Parameters: - r (scalar) – number of rows of resulting matrix.
- c (scalar) – number of columns of resulting matrix.
- loc (matrix, vector or scalar) – location parameter, scalar or ExE conformable matrix with r and c.
- scale (matrix, vector or scalar) – scalar or ExE conformable matrix with r and c.
- 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: - x (RxC matrix) – Laplacian distributed random numbers.
- newstate (Opaque vector) – the updated state.
Remarks¶
The properties of the pseudo-random numbers in x are:
\[\begin{split}E(x) = location\\
Var(x) = 2*scale^2\end{split}\]
r and c will be truncated to integers if necessary.
