Fill a vector with zeros

I have a vector difined as:

    n=n1:n2

I want to make another vector of the same size as n called x, but with just a n0 value, and the others as zeros. Example:

    n0=1
    n1=-2
    n2=2

So the vector n will be n = [-2 -1 0 1 2] and the x vector should be: x = [0 0 0 1 0]

Any idea aboud how can I do that?

n(n~=n0) = 0;

Answer 2

One approach:

n0=1;
n1=-2;
n2=2;
n=n1:n2;
nz = zeros(size(n));
nz(n==n0) = n0

nz =
     0     0     0     1     0

¿What about if i want that since the n0 value every value is n0?

[Star Strider]

If you want every value of the new vector to be ‘n0’, the new vector becomes:

nz = ones(size(n))*n0;

Please give an example of what you want if it is something other than what I describe here.
