C#

public static DoubleMatrix Dense(
	int numberOfRows,
	int numberOfColumns
)

VB

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

C++

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

F#

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

Parameters

numberOfRows Int32: The number of matrix rows.
numberOfColumns Int32: The number of matrix columns.

Return Value

DoubleMatrix
The matrix having the specified size.

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 zero.

Creation of a dense matrix with all entries equal to zero

using System;

namespace Novacta.Analytics.CodeExamples
{
    public class DenseExample5  
    {
        public void Main()
        {
            // Set matrix dimensions.
            int numberOfRows = 3;
            int numberOfColumns = 2;

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

// Executing method Main() produces the following output:
// 
// Each entry is equal to zero.
// The data matrix:
// 0                0                
// 0                0                
// 0                0                
// 
//
