ComplexMatrixDivide Method (ComplexMatrix, Complex)

Determines the division of a matrix by a scalar.

Namespace:  Novacta.Analytics
Assembly:  Novacta.Analytics (in Novacta.Analytics.dll) Version: 2.0.0
Syntax
public static ComplexMatrix Divide(
	ComplexMatrix left,
	Complex right
)

Parameters

left
Type: Novacta.AnalyticsComplexMatrix
The left operand.
right
Type: System.NumericsComplex
The right operand.

Return Value

Type: ComplexMatrix
The result of dividing left by right.
Exceptions
ExceptionCondition
ArgumentNullExceptionleft is null.
Remarks

Let LaTeX equation and LaTeX equation be the left number of rows and columns, respectively, and consider its generic entry

LaTeX equation

The method returns a matrix having the same dimensions of left, whose generic entry is:

Examples

In the following example, a matrix is divided by a scalar.

C#
using System;
using System.Numerics;

{
    public class ComplexDivisionExample1  
    {
        public void Main()
        {
            // Create the left operand.
            var data = new Complex[6] {
                new Complex(1, -1), new Complex(5, -5),
                new Complex(2, -2), new Complex(6, -6),
                new Complex(3, -3), new Complex(7, -7)
            };
            var left = ComplexMatrix.Dense(3, 2, data, StorageOrder.RowMajor);
            Console.WriteLine("left =");
            Console.WriteLine(left);

            // Create the right operand.
            Complex right = new(2, -2);
            Console.WriteLine("right =");
            Console.WriteLine(right);

            // Divide left by right.
            var result = left / right;

            Console.WriteLine();
            Console.WriteLine("left / right =");
            Console.WriteLine(result);

            // In .NET languages that do not support overloaded operators,
            // you can use the alternative methods named Divide.
            result = ComplexMatrix.Divide(left, right);

            Console.WriteLine();
            Console.WriteLine("ComplexMatrix.Divide(left, right) returns");
            Console.WriteLine();
            Console.WriteLine(result);

            // Both operators and alternative methods are overloaded to 
            // support read-only matrix arguments.
            // Compute the division using a read-only wrapper of left.
            ReadOnlyComplexMatrix readOnlyLeft = left.AsReadOnly();
            result = readOnlyLeft / right;

            Console.WriteLine();
            Console.WriteLine("readOnlyLeft / right =");
            Console.WriteLine(result);
