what does frommatrix() do in Javascript when affected to a JitterMatrix object?

couldn't find a reference notation about frommatrix() anywhere when reading jitter tutorial 46.

Also, just in case the devs are reading this, this block of text from tutorial 46, "First we copy plane 0 of distmat (the squared x distances) into z distances) into summat2." seems worded a little funky, maybe its just me...
