I need help with (hopefully) just one more thing. I have been fussing with this for quite some time and have decided just to give up and ask! I want to match a column in a matrix to a vector. I found a "which" command that I thought would be helpful as it does the following:
As the above gave which placement in the g vector corresponded to 5 (the second place), I need this command to give me which column in a matrix matches to a vector.
This is just a toy example of what I am trying to do:
This does not work, and with my "real" matrices and vectors, I was getting outputs that did not make sense. These examples are more to give an idea of what I am aiming to accomplish.
Thank you for all the help!!
