LinearAlgebra

  

Row

  

return a sequence of row Vector(s) from a Matrix

  

Column

  

return a sequence of column Vector(s) from a Matrix

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

Row(A, L, options)

Column(A, L, options)

Parameters

A

-

Matrix

L

-

integer, range with integer endpoints, or list of integers and/or ranges with integer endpoints; represents a row (column) selection

options

-

(optional); constructor options for the result object

Description

• 

The Row(A, L) (Column(A, L)) function returns an expression sequence of one or more row (column) Vectors corresponding to the specified rows (columns) of Matrix A, as determined by the selection parameter L. For more information regarding parameter L, see Matrix and Vector Entry Selection.

• 

The constructor options provide additional information (readonly, shape, storage, order, datatype, and attributes) to the Vector constructor that builds the result. These options may also be provided in the form outputoptions=[...], where [...] represents a Maple list.  If a constructor option is provided in both the calling sequence directly and in an outputoptions option, the latter takes precedence (regardless of the order).

  

If constructor options are specified in the calling sequence, each resulting Vector has the same specified options.

• 

This function is part of the LinearAlgebra package, and so it can be used in the form Row(..) only after executing the command with(LinearAlgebra). However, it can always be accessed through the long form of the command by using LinearAlgebra[Row](..).
