This question is exhaustively answers by the Getting Started chapters of the documentation. It is strongly recommended to read these chapters, if you want to use such a powerful language as Matlab.

A = [1 2 3;4 5 6]
B = [7;8]
C = [A,B]
or
C = A;
C(:,end+1) = B

Try this little demo. It should be rather self explanatory and fairly robust:
% Generate some sample data
rows = 4;
M = magic(rows)
columnToInsert = ones(rows,1)
% Append the column.
appendedM = [M columnToInsert]
% Prepend the column.
prependedM = [columnToInsert M]
% Insert the column in the middle somewhere.
newColNumber = 3;
insertedM = [M(:, 1:newColNumber-1), columnToInsert, M(:, newColNumber:end)]
