I want to construct a row vector, with say, "L zeros", followed by a "1", and then again followed by "L Zeros"
What is the easiest command to do that? For example a= [ (0 0 0 ... L-1(0)) 1 (0 0 0 ... (L-1) 0)]

L = 5; % or L = 1000
out = [zeros(1,L),1,zeros(1,L)];

Make a row zero matrix...and place one at the indices you want....
or
k = repmat([0 0 0 1],1,4)

Hi Dr Kolukula
What I am trying is just a single "1" in the centre of the row vector, with zeros preceding and following it. The length of the matrix can be anywhere from a few 10s to 1000s. I am looking for a simple generic command. As you see I am new to MATLAB.
