Embedded Files
I have been working on some assignments as Teaching Assistant in King Fahd University, and in it, I was tasked to convert about 50 pages of scanned documents to a Microsoft Office Word file, the file contained a lot of equations and Matrices, and I had to make things easy for my self. I learned few small tricks here and there that I'm going to share them here in this page, I hope you find this useful.
First Tip is related to inserting a matrix of higher dimension, First of all, to insert any equation in Word the keyboard shortcut for Windows is "alt"+ "=". For a Mac system, the shortcut is control + "=".
As seen in the GIF below, a matrix is added using \matrix , and to set the row and line number you repeat the symbols "&" and "@" respectively n-1 times. 4x4 matrix means 3 x "@" and 3x "&". Honestly, I don't know if this is a shortcut or just as cumbersome as the other methods you find out there. and I was using Office 2013 so, I'm not sure yet if any update has been made in this.
The symbol " & " without quotes is for columns of the matrix, to enter a column vector of 4, you specify n-1 of " & " and same if you want to add row vector, you just specify n-1 of "@ " and you are done, of course, for matrices larger than lets say 10, it can become tedious to type "@" 9 times. so this remain somewhat useful for low to medium size matrices which is what most of us deal with.
To be continued with new things I find in Word...
