Excel Macro Example: Sun Rise, Set, Transit, Twilight

The purpose of this project is to demonstrate how to interact with an Excel xlsm file to write inputs and read outputs from the Excel calculation. For this example, the matlab code sets the inputs of location and time, and reads the values calculated by the spreadsheets: Sun's rise, set, transit, and twilight.

The download includes the spreadsheet xlsm files. The xlsm extension is the spreadsheet that enables visual basic macros. The .BAS file and a text file explaining how to create your own calculator spreadsheet is included in the download.
