Adding 2 matrices together in matlab, got errors instead

Hello, I'm trying to add an existing matrix to another matrix, specifically i'm adding an additional column of numbers to another grid. I've tried multiple methods from matlab's suggestions but none worked and I keep getting "Dimensions of arrays being concatenated are not consistent."

For references:

a= [1 2; 3 4; 5 6]

b= [1;2;3]

My goal is to add "b" to the right side of "a" as an additional column of numbers without getting the error. If anyone can show me their input it'll be much appreciated!
