LinearAlgebra[Modular]

  

Random

  

create a new mod m Matrix or Vector containing random values

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

Random(m, nrow, ncol, dtype, order)

Parameters

m

-

modulus

nrow

-

number of rows in output object

ncol

-

number of columns in output object

dtype

-

datatype of output object

order

-

(optional) ordering of output object

Description

• 

The Random function creates a new mod m Matrix or Vector of the specified type and dimensions, assigning to each entry a uniformly distributed random value in the range 0..m1.

  

A row Vector can be obtained by setting nrow&equals;0, and a column Vector by setting ncol&equals;0. If 0<nrow and 0<ncol, a Matrix is produced. If nrow&equals;0 and ncol&equals;0, an error results.

• 

The allowable datatypes are hardware integer (dtype=integer[4]/integer[8] or integer[]), hardware float (dtype=float[8]), or Maple integer (dtype=integer). If specified, order can be C_order or Fortran_order. If order is not specified, C_order is used.

• 

This command is part of the LinearAlgebra[Modular] package, so it can be used in the form Random(..) only after executing the command with(LinearAlgebra[Modular]).  However, it can always be used in the form LinearAlgebra[Modular][Random](..).
