Math Editor

Welcome to the Playground

Let's take a test drive

The main goal of Math Editor is to make writing math reports as easy as possible. Let's investigate this claim together!

Math

We use MathLive web component because it makes writing LaTeX effortless with its virtual keyboard.

This is a centered block of the famous quadratic formula:

x=2a−b±√b2−4ac​​

You can also inline it: f(x)={10​∣x∣<1∣x∣>1​ is called a gate function.

MathLive supports over 800 TeX commands. you can view the full list Here.

Graph

We use GeoGebra to graph functions of one or two variables.

Sketch

We use Excalidraw to sketch hand-drawn like diagrams.

Code

Here's some C# code

static class MatrixExtensions
{
  // Extension methods
  // read matrix from console
  public static void ReadMatrix(this double[,] matrix)
  {
    int rows = matrix.GetLength(0);
    int cols = matrix.GetLength(1);
    // read matrix size from console if not provided
    if (rows == 0 || cols == 0)
    {
      WriteLine("Enter number of rows");
      int.TryParse(ReadLine(), out rows);
      WriteLine("Enter number of columns");
      int.TryParse(ReadLine(), out cols);
    }

    for (int i = 0; i < rows; i++)
    {
      for (int j = 0; j < cols; j++)
      {
        WriteLine("Enter element [{0}][{1}]", i + 1, j + 1);
        double.TryParse(ReadLine(), out matrix[i, j]);
      }
    }
  }

  // print matrix to console
  public static void PrintMatrix(this double[,] matrix)
  {
    for (int i = 0; i < matrix.GetLength(0); i++)
    {
      for (int j = 0; j < matrix.GetLength(1); j++)
      {
        Write("{0,4}", matrix[i, j]);
      }
      WriteLine();
    }
  }
}
