How to insert an element into matrix?

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, :)]

how to get variables with suffix , in matrix for..as following

x1 y1 txy1

x2 y2 txy2

x3 y3 txy3

x4 y4 txy4

[Image Analyst]

I don't know what you mean. What suffix? Do you have scalar variables with those names and want to build a matrix from them? Like

M = [...
x1 y1 txy1;
x2 y2 txy2;
x3 y3 txy3;
x4 y4 txy4]

What is "the first one"? Please explain. Why do you want loops?

 result = [A;B]

Or use cat()
