ComplexMatrixRowIndex Property

Gets or sets the index of the ComplexMatrixRow.

Namespace:  Novacta.Analytics
Assembly:  Novacta.Analytics (in Novacta.Analytics.dll) Version: 2.0.0
Syntax
Copy
public int Index { get; set; }

Property Value

Type: Int32
The index of the ComplexMatrixRow.
Exceptions
ExceptionCondition
ArgumentOutOfRangeExceptionvalue is less than zero.
-or-
value is greater than or equal to the NumberOfRows of the matrix of which this instance represents a row.
Remarks

In a matrix, entries are arranged in rows and columns. Zero-based indexes are assigned to rows and columns, so that each entry can be identified by the indexes of the specific row and column on which it lies.

A ComplexMatrixRow instance represents a row of a ComplexMatrix. More thoroughly, since each ComplexMatrixRow is an item in a ComplexMatrixRowCollection, such matrix can be inspected by getting the Matrix property of the given collection.

Property Index is the zero-based index assigned to the row in that matrix.

Examples

In the following example, the Index of a ComplexMatrixRow is modified, and its XData property is evaluated before and after that change.

            var rows = matrix.AsRowCollection();

            // Set the column corresponding to property XData.
            rows.XDataColumn = 1;

            // Get the a row in the collection
            var firstRow = rows[1];

            // Get the XData value of the row.
            Console.WriteLine("XData for Row {0}: {1}", firstRow.Index, firstRow.XData);
            Console.WriteLine();

            // Change the index of the row.
            firstRow.Index = 3;

            // Here the row represents the matrix row having index 3.

            // Get the XData value of the first row.
            Console.WriteLine("XData for Row {0}: {1}", firstRow.Index, firstRow.XData);
