a=randi([0 27],1,50)
padarray(a,[1,1],0)  % requires image processing toolbox

if i want padding 3 zero form all side in need:

a=randi([0 27],1,50)

padarray(a,[3,3],0)

its true?

Yes correct , make sure to accept the answer if it helped.

This answer not correct.

if a=[ 1 2 3 4 5 6 7]

after the padding it will be:

[ 0 0 0 1 0 0 0 2 0 0 0 3 0 0 0 4....]

how i do this?

[madhan ravi]

ok try this:

a=[ 1 2 3 4 5 6 7];
b=zeros(1,numel(a)*3+numel(a));
b(4:4:end)=a(:)

command window:

b =
  Columns 1 through 13
     0     0     0     1     0     0     0     2     0     0     0     3     0
  Columns 14 through 26
     0     0     4     0     0     0     5     0     0     0     6     0     0
  Columns 27 through 28
     0     7
