Linear Format Version 3

There is basically no documentation on the /eqarray command so I'll post a quick example that I had to figure out from trial and error:

\eqarray(Z-3x_1&-5&x_2&-6&x_3&&&&=&0 @ 2x_1&+&x_2&+&x_3&+x_4&&&=&4 @ x_1&+2&x_2&+&x_3&+&x_5&&=&4 @ x_1&+&x_2&+2&x_3&+&&x_6&=&4 @ x_1&+&x_2&+&x_3&+&&&x_7=&3)

Basically it aligns each sequential ampersand in the equations. That's why the first one need four extras (corresponding to the gaps caused by the lack of x_4-7).

Hope this gets added into Google's search results for "eqarray" because I had a heck of a time finding information about the command.

We're thinking about importing/exporting LaTeX in math zones. Kind of handy when you want to copy an equation from Wikipedia, among other sources. Or maybe LaTeX is in your fingers. Hopefully we'll have the resources to add this functionality.

What about importing LaTeX? What is the progress with that?

I don't know how is it possible, but in Office 2010 RTM 64bit (build 14.0.4760.1000) except Word, I can display the equation number using the equation-array method of displaying equation numbers. Maybe it is caused by the fact that on the computer, where I try it, Office 2010 Beta (32bit) was install before, and some settings wasn't deleted during reinstallatio(?) - I don't know, but it is surprise for me too. Probably, after reinstalling Windows and clean installation of Office, situation would change (but I cannot check it).

Please sorry for misunderstanding, and sorry for this and previous post, but I write only what I found out.

Unfortunately in the shipping versions of PowerPoint and OneNote, the equation-array method of displaying equation numbers described by Nali doesn't work. While prototyping the more elegant equation number display described in my post on Equation Numbering Prototype, I checked in a change to use that instead of the equation-array method. The more general method includes line breaking, whereas the equation-array method only works with a single line. But it was too late to enable the more general method in Office 2010. Later when I realized that the equation-array method was disabled as well, it was too late to make any changes that didn't involve security or data loss. I'm very sorry. On a lighter note, the shipping version of OneNote 2010 does use math italic in math zones unless the user disables it.

Hello, I found another issue in OneNote.

OneNote creates all equation variables in upright (unslanted) face by default, but they should by in italics. I always must switch them to italics manually.

Please, is there any way to set the italics as the default font for variables?

Thanks.

Jeffrey:

In OneNote and PowerPoint, it is possible to add the equation number into equation manually (as described in Linear format):

Your equation must be in "Display" mode. In "displayed" equation, you must create an "Equation array" (keyword \eqarray), and inside the array, type your equation (e.q. E=mc^2) - so you have \eqarray(E=mc^2). After buildup the array and equation, you must return the cursor back into the equation array (behind your equation, e.q. E=mc^2, but "inside" the equation array) and type # (keyword \eqno<space> does not work). After that, cursor moves automatically to the right side of math paragraph, and you can type there some text or manual number for your equation - so your equation is centered and the equation number is on the right side of paragraph.

It works in PowerPoint, Excel, and OneNote, but it does not work in Word.

Hello,

That worked brilliantly; thanks!

Cheers,

\quad should work in the released version, but I don't see \qquad there. You can define \qquad in OneNote by clicking on the Tools option in the math ribbon, which brings up the math autocorrect dialog. Type \qquad in the Replace box and 2003 alt+x 2003 alt+x in the With box. The alt+x converts the Unicode value of an em space (2003) into the actual character. So with this definition, typing \qquad (followed by a delimiter) inserts two em spaces into your document. If you need more spacing, you could define \qqquad, etc.

The equation numbering doesn't work in Office 2010 :-(. Sorry about that. Equation numbering is the most highly requested feature except for more documentation. Hopefully documentation will improve shortly and that equation numbering will find its way into the next version of Office.
