It is the circle structuring element, in binary form (which is the form required by the operators)
I suggest using N = 0 or N = 6.

I assume you mean for morphology, like imerode(), imclose(), imopen(), imdilate(), etc. For that you need the Image Processing Toolbox.

rcjr15's reply moved from an "Answer" to here:
ya in those morphological operation if I want to use a circular structural element should that require any other toolbox? for. eg. to use strel('circle',radius)??

Then my answer is definitely confirmed - you need the Image Processing Toolbox.

Are you looking for a solid ring or an outline?
If you are looking for an outline, you could do something like,
R = 10; %radius. Final size will be (2*R-1)x(2*R-1)
%create a disk
t1 = strel('disk', R);
%put a row of 0 around it
t2 = false(2*R+1, 2*R+1);
t2(2:end-1, 2:end-1) = t1.Neighborhood;
%take the outline
t3 = logical(t2 - imerode(t2,strel(ones(3,3))));
%and trim the padding
strel_circ = t3(2:end-1,2:end-1);
