MATLAB GUI Implementation for Various Interpolation Methods with Source Code

This program implements a MATLAB-based graphical user interface (GUI) for demonstrating and comparing various interpolation methods. The application allows users to select between different interpolation techniques such as linear interpolation, spline interpolation, and bilinear interpolation through interactive GUI components. Users can input relevant parameters to perform interpolation operations, with the program handling data processing through MATLAB's built-in interpolation functions like interp1, interp2, and spline. The interface features comparative visualization that displays both original data points and interpolation results simultaneously, enabling intuitive evaluation of different methods' performance. The GUI is built using MATLAB's App Designer or GUIDE framework, incorporating callback functions for user interactions and data plotting capabilities through MATLAB's graphics system. This implementation provides a practical tool for comparing interpolation techniques, offering valuable insights for data processing and image reconstruction applications in real-world scenarios.
