I’m sorry if this seems like a basic question, but I’ve been pulling my hair out trying to figure this out. I’m an infrequent PHPer at best, and that makes even simple stuff difficult
I have a list of values for each state… it looks like this
I want to go through and calculate absolute differences and plop those into a matrix (I have managed to already create that).
So it should look like this:
state1 state2 state3
state1 0 .1 .2
state2 .1 0 .3
state3 .2 .3 0
Try as I might I’m coming up short on how to do this… can you think of an easy code to do it offhand?
