for example, i have a vector A = [ which has 43 elements ]
if i use reshape (A,9,5)
there is an error since i lack 2 elements to make a 5x9 table. how do i add empty elements to the matrix?

You haven't specified where the padding should go (beginning/end) and with what values, but this should give you the idea:
A(45)=0; %pad the vector with zeros
B=reshape (A,9,5)

With cell arrays, you can do something like that,
A=num2cell(A);
A{45}=[]; %pad with empty
B=reshape(A,9,5);
As for "padding in random places", you can do things like this:
A=num2cell(A);
B=cell(9,5);
B(1:20)=A(1:20);
B(23:end)=A(21:end);
