    using Aspose.Cells;
    using Aspose.Cells.Drawing;
    using Aspose.Cells.Drawing.Equations;
    using System;

    public class EquationsClassArrayEquationNodeDemo
    {
        public static void Run()

            // Create a new workbook
            Workbook workbook = new Workbook();
            Worksheet worksheet = workbook.Worksheets[0];

            // Add a text box shape to hold the equation
            var textBox = worksheet.Shapes.AddTextBox(0, 0, 0, 0, 100, 100);

            // Create an array equation node (must be created with parent node)
            ArrayEquationNode arrayEquation = (ArrayEquationNode)EquationNode.CreateNode(EquationNodeType.ArrayEquation, workbook, null);

            // Create a simple equation node to add to the array
            // EquationNode is abstract, so we need to create a specific type
            // Using Text equation type as the simplest option
            EquationNode simpleEquation = EquationNode.CreateNode(EquationNodeType.Text, workbook, arrayEquation);

            // Add the simple equation to the array equation
            arrayEquation.AddChild(simpleEquation);

            // Set the equation to the text box
            textBox.Text = arrayEquation.ToMathML();

            // Save the result
            workbook.Save("ArrayEquationNodeDemo.xlsx");
        }
    }
