Functions and Solver Improvements in Excel 2010


There have been several improvements made in Excel 2010 to the function library and the Solver add-in. The function improvements have been made to address issues reported in academic papers as well as customer feedback. To quote the Excel team blog:


“In Excel 2010, we made many improvements to Excel’s function library. Excel 2010 will feature an accurate and consistent function library while remaining compatible with previous versions of Excel. “


In addition to the accuracy improvements, we also have introduced various new functions to the Excel function library to ensure that users have a consistent function library with implementations that match standard practices. As are result of these improvements, we have also made some UI changes to help users adopt the new functions.

    Hello,

    the solver in the beta version is unusable and more, when you close excel, a password box prompts, forbiding you to close excel properly without using the task manager.

    What can i do?

  5. asdfg says:

    you have to click on "cancel" a few times and than the box won’t come again until your next excel-session.
