Flatten a square matrix in Mathcad

Mathcad is awful,

If you like me are being forced to use Mathcad after several blissful years of Mathematica then you get very sad very fast.

Here is a function to flatten a square array of square arrays in Mathcad (click to pop)

It could be extended to non-square arrays by adding a few more arguments. The advantage over the stuff on this page (current top google hit : http://communities.ptc.com/thread/38326 ) is no if-else statements and it works on matrices, not just vectors. Note the ORIGIN is set to 0

More importantly the whole mess can be avoided with creative use of the augment and stack function for array building

A .mov that works in Mac Powerpoint 2011 via quicktime export.

Hey have you ever made a quicktime movie in final cut pro only to not have it work in powerpoint?

I made a movie (.mov) using final cut on a university computer and though it would play locally on my laptop in Quicktime it would not work in powerpoint. I do not have final cut or quicktime pro on my laptop.

I tired using VLC to convert it to an avi, but it would drop frames including the last one.

To do a quick conversion to get it to work open the .mov in quicktime and select File -> Export...

On the Formats Menu select anything, like 720p for instance, and export the movie.

Try it in powerpoint!
