Numerical Analysis Library for C# Projects

Library for numerical analysis, designed to help solve a variety of mathematical and computational problems. Additionally, the repository includes a folder named ProjectsToTestLibrary, which contains example projects demonstrating how to use the library.

Installation

1. Download the latest release from the Releases page. Click on numerical-methods.dll, or download it directly here.

2. In Visual Studio, right-click on the References section of your project, select Add Reference..., and click the Browse... button in the lower-right corner of the window. Choose the downloaded numerical-methods.dll file.

   • Path: References (right-click) ➔ Add Reference... ➔ Browse... ➔ Choose numerical-methods.dll.

3. Include the following line in your C# project:

   using NumericalMethods;

Features

Library has methods that help solving:

• Linear Equation Systems
  • Cramers rule
  • Gauss Method
  • Jordan Gauss Method
  • Inversion Method
  • Seidel Method
  • Simple Iteration Method
• Data tables
• LU-decomposition
• Matrix functions and operations
• Non-linear equations roots (using dichotomy)
• Numeric Serius Sum
• Tangent

Example of usage

For example let's test "Data table" with the project to test a library located below:

NumericalMethods\ProjectsToTestLibrary\DataTableTest\DataTableTest.cs

using System.IO;
using DataTable = NumericalMethods.DataTable;
using FilesController = NumericalMethods.FilesController;
using GraphicsForm = NumericalMethods.GraphicsForm;

namespace DataTableTest
{
    class DataTableTest
    {
        static void Main(string[] args)
        {
            using (StreamWriter writer = FilesController.WriteResultToFile("DataTableResult.txt"))
            {
                DataTable table = new DataTable("TestTable.txt", "Data Table Graphic");
                string txt = $"\r\n\r\n\r\n Read lines: {table.Length,0}";
                txt += table.ToPrint("   Processing file *.txt");
                writer.WriteLine(txt);
                GraphicsForm.SingleGraphic(table, widthPointsCount: 300, heightPointsCount: 500);
                table.ToTxtFile("DataTableAdditionalResult.txt", " New results form");
            }
        }
    }
}

See README_TestTable.txt

Running the app

Running this example generates files DataTableResult.txt and DataTableAdditionalResult.txt, in the same folder as the .exe file.

DataTableResult.txt

DataTableResult.txt

 Read lines: 200   Processing file *.txt

 Table Data Table Graphic in file TestTable.txt:
 
  x = [   4.300000000000   :   8.600000000000  ]   x_Reg =   4.300000000000

    Min (    4.710552763819,     0.467901053830 )
    Max (    7.908542713568,     6.751486519887 )    f_Reg =   6.283585466057

 Zeros Table of Data Table Graphic is empty!

DataTableAdditionalResult.txt (being the same as it should)

New results form

 Function table Data Table Graphic : 
 
  x = [   4.300000000000   :   8.600000000000  ]   x_Reg =   4.300000000000

    Min (    4.710552763819,     0.467901053830 )
    Max (    7.908542713568,     6.751486519887 )    f_Reg =   6.283585466057

 Zeros Table of Data Table Graphic is empty!
 

Running the app will also open a window displaying the graphic representation picture of the .txt-file data.
