1. The problem statement, all variables and given/known data 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. 2. Relevant equations I think ones(,) is supposed to help? 3. 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.
