CMatrix:GetRow

The GetRow method returns a reference to the CArray at the specified row.

Syntax

nRow = CMatrix:GetRow( nIndex )

where

nIndex is the row index of the member to retrieve.

nRow is a reference to the CArray at row index nIndex. On failure, nil is returned.

Each row of the CMatrix is a reference to a CArray containing (column, value) pairs. This method returns a reference to the row object at index nIndex.

Example

Assume that a CMatrix named M exists and contains a value "abc" at index [10][5]. This script shows working with the returned row as a CArray:

r = M:GetRow(10)	-- return a reference to row 10
if ( r and r:Exists(5) ) then	-- check that row r exists and column 5 exists
v = r:Get( 5 )	-- get the value of M[10][5]
Printf("v = '%s'", v )	-- v = 'abc'
end
