Subject: dot product and vectors with imaginary numbers From: Linda Davis Date: 6 Jul, 2010 23:59:04 Message: 1 of 18 
Ok, so I'm reviewing my math in order to get up to speed with what I want to do in MatLab. I'm using a couple of selfteaching books, making sure I go from beginning to end, so that I don't drown when doing the programming I need to do. I've stumbled with something simple and feel stupid. I'm given a column vector with imaginary numbers; I'm learning to use the dot product for a matrix with imaginary numbers. I am really, really rusty with respect to "i" and using "i." I know i^2=1
