Cursor function when studying .mat figures.

Function/Cursor_Function.m

+%% Function Description (Cursor Function)
+% The `Cursor_Function` enhances plot interactivity by customizing data tips in MATLAB plots. It dynamically
+% generates detailed tooltips that display the departure and arrival dates, the time of flight (TOF), and the delta-v
+% (∆V) based on the cursor's position over plot data points. This function is typically used to provide additional
+% context for data points in plots related to time series or trajectory analyses, improving data readability and
+% user interaction.
