C#

public static DoubleMatrix Dense(
	int numberOfRows,
	int numberOfColumns,
	double data
)

VB

Public Shared Function Dense ( 
	numberOfRows As Integer,
	numberOfColumns As Integer,
	data As Double
) As DoubleMatrix

C++

public:
static DoubleMatrix^ Dense(
	int numberOfRows, 
	int numberOfColumns, 
	double data
)

F#

static member Dense : 
        numberOfRows : int * 
        numberOfColumns : int * 
        data : float -> DoubleMatrix

Parameters

numberOfRows Int32: The number of matrix rows.
numberOfColumns Int32: The number of matrix columns.
data Double: The value assigned to each matrix entry.

Return Value

DoubleMatrix
The matrix having the specified size and data.

Remarks

DoubleMatrix dense instances allocate storage for each matrix entry. Sparse DoubleMatrix instances can be created by calling method Sparse(Int32, Int32, Int32).

Example

In the following example, a dense matrix is created having all its entries equal to a given value.

Creation of a dense matrix with all entries equal to a given value

using System;

namespace Novacta.Analytics.CodeExamples
{
    public class DenseExample4  
    {
        public void Main()
        {
            // Set matrix dimensions.
            int numberOfRows = 3;
            int numberOfColumns = 2;

            // Set the value for each entry.
            double data = -1.0;

            // Create the matrix. All entries will be equal to the
            // same value.
            var matrix = DoubleMatrix.Dense(
                numberOfRows, numberOfColumns, data);
            Console.WriteLine("Each entry is equal to the same value.");
            Console.WriteLine("The data matrix:");
            Console.WriteLine(matrix);
        }
    }
}

// Executing method Main() produces the following output:
// 
// Each entry is equal to the same value.
// The data matrix:
// -1               -1               
// -1               -1               
// -1               -1               
// 
//
