Suppose I have a matrix A = ones(4,6). I want to combine it with a vector B = zeros(1,6) to make another matrix C of size 5 by 6, where the first four rows would be ones and fifth would be zero.

Here's code to do both inserting (like your subject line) and appending (like your message body):
A = ones(4,6)
B = zeros(1,6)
% To append / concatenate:
C = [A; B]
% To insert into a specified row number:
rowToInsert = 3 % Whatever you want.
C = [A(1:rowToInsert-1, :); B; A(rowToInsert:end, :)]
