We did a test review today on matrix modelling. we learned four sections.
Matrix intro Matrix operations
*vocab * +
*naming * -
*calculator *scalar x
*matrix x
2. Matrix multiplication in context
(can you use it to speed up calculations?)
*AVOID "non-sense" CALCULATIONS

3.Transition matricies
*row by square
*"1 sums"
*loopies
*[b] * [a] ^n / [b] * [a] (n+1)

4. Networks
Directed Non-directed
one ---> two way <---->

node, direct route, "at most" "exactly"
[a] vs. [a]^2 vs. [a]^3 ...etc....
