adding a padding to matrix.

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?

[Portgas Ace]

so there is a value of a matrix which will only be a space.

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)

[Portgas Ace]

could i possibly do

A(45)= ' ' %pad with only a blank

also, is there any other way to put the paddings on random places.

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);
