Matlab, adding columns in matrices

[slugbunny]

Homework Statement

I need to create a function for scilab which adds a row of zeros to the right of an nxn matrix, a.
I also have to add a row of 6's at the bottom but I think i have that part down.

Homework Equations

I think ones(,) is supposed to help?

The Attempt at a Solution

I have tried to use ones...

function m_1=matrix_1(a,n)
m_1=[a,0*(ones(n;1))]
endfunction

I figure if [a;ones(1,n)] gives 1 row and n columns (at the bottom), then [a,ones(n;1)] should make n rows and 1 column. Instead I have an error 'waiting for right parenthesis.'

I have also thought of zeros but I don't know how to add n rows of zeros since you must type [0;0;0...] for each row.

Sorry, I realize there is a math & science software forum.

u should do
m= [a zeros(1,size(m,2))];
