Help with the equation in making groups.

i cant think of a syntax to do this.

for example #students : 43

min number of students per group: 2 max number of students per group: 3

%there will be 13 groups with 3 members and 2 groups with 2 members.

what if min =3, max = 4?

%there will be 10 groups with 4 members and 1 group with 3.

and so on. it differs depending on the given. i cant think of a syntax for this. :/

min1 = 2;
max1 = 3;
s = 43;

ns = fullfact(floor(s./[min1 max1]));
out = ns(find(ns*[min1 max1]' == s);

OR without fullfact

min1 = 2;
max1 = 3;
s = 43;

ns = floor(s./[min1 max1]);
[x y] = ndgrid(1:ns(1),1:ns(2));
ns1 = [x(:) y(:)];
out = ns1(ns1*[min1 max1]' == s,:);

what is full fact?

[Andrei Bobrov]

fullfact - function from Statistics Toolbox

fullfact doesn't work in my matlab. :(
