Using convolve 4/9
Session Links
  • To do the homework you’ll need to install the Convolve macro as an Excel add-in on your computer
  • If you installed the Special Tools for This Course, then you’ve already installed Convolve.
  • Please do not copy the Convolve macro into your homework workbooks
  • For your own personal use, you might want to include Convolve in workbooks
    • Some people who use your work might not have Convolve
    • Some computers you use might not have Convolve

For this course, we require that when you use Convolve, you use it as part of the add-in package we provide, mostly because we don’t want you to include the macro in your workbooks. When it’s included in your workbook, we can’t tell whether you have a legitimate macro or a possible virus infection. For safety’s sake we require that when you use Convolve, you use it from the add-in.

But even if you know that you’re in a virus-safe environment, it’s still a good idea to prefer the add-in approach to that of installing needed macros in workbooks. Let’s say that your work group or organization is sharing some Excel workbooks, and that you need access to some custom functions, such as Convolve. If you install them in add-ins that everyone has access to, then when you add new functions or enhance the capabilities of existing functions, everyone will get the additions “for free.” By comparison to the approach of installing the capability in workbooks, you’re more assured of consistency and you face a simpler upgrade task when you upgrade.

There is a downside to the centralized add-in approach. If you decide to change the way an existing worksheet function is invoked, or if you change the way it returns its values, you must remain compatible with the established uses of that function. Welcome to the problems of software support.

Avoid Unnecessary Spaces in Formulas

The space character, in many cases, doesn’t change the value of a formula. For instance, these two formulas return the same value:

  • =A1 + 2
  • =A1+2

Some people think that well-placed spaces make formulas easier to read. Although that might be true, the practice is both inconvenient and extremely dangerous. More

Keyboard Power Tips

Excel’s online help, and many of the how-to books you can buy, provide long lists of keystroke shortcuts for carrying out specific operations, such as inserting rows, selecting regions, or deleting columns. And they are useful.

But the true power of the keyboard comes not from using these particular commands. Rather, it comes from learning combinations that are useful for particular situations that you encounter frequently.

For instance, there’s no command for deleting the rows that contain the selected cells, but there is a combination:

  • Shift+Space selects the rows that contain the selection.
  • Ctrl+- deletes the now-selected rows.

And so, Shift+Space Ctrl+- deletes the rows containing the selection.

Learning a vast array of keystroke commands is probably less useful than learning the keystroke combinations that do exactly what you need to do most often.
