How to stick on/augmenting a vector into the matrix?

If i have a matrix like this:
2 1 4 6 2
9 4 6 1 2
5 3 2 8 3
7 2 1 9 3
7 1 8 2 4
3 5 4 1 2
then i want to stick on a vektor contain of "1" in the beginning of that matrix. so it'll be like this:
1 2 1 4 6 2
1 9 4 6 1 2
1 5 3 2 8 3
1 7 2 1 9 3
1 7 1 8 2 4
1 3 5 4 1 2
what to do? thanks before :')

I'm a student just learning how to use MATLAB... but I'm pretty sure you can use the horzcat function to do it easily. Matlab has documentation on it.
https://www.mathworks.com/help/matlab/ref/horzcat.html
The [] operator defaults to horzcat, so the solution I listed
[ones(size(TheMatrix,1),1), TheMatrix]
is really the same as
horzcat( ones(size(TheMatrix,1),1), TheMatrix)

NewMatrix = [ones(size(TheMatrix,1),1), TheMatrix];

then the result is like this:
1 1 1 1 1 1 2 1 4 6 2
1 1 1 1 1 1 9 4 6 1 2
1 1 1 1 1 1 5 3 2 8 3
1 1 1 1 1 1 7 2 1 9 3
1 1 1 1 1 1 7 1 8 2 4
1 1 1 1 1 1 3 5 4 1 2
is there another solution?
