Hello,

First of all, this is my first topic in the forum. I'm from Spain and thus, my english is not very fluent. A apologize for it.

I'm trying to describe an experiment and I have some problems where describing it.

I have a set M of samples. Each sample x (in) M, is composed by the next elements:

x = { t, m, h_a, h_b, j_a, j_b, k_a, k_b}

(h_a can be viewed as h(subindex)a)

t is a value between 0 and 100

m is a value of {1,2,3,4,5}

h_a, h_b is a pair of values regarding an specific feature H

j_a, j_b is another pair regarding another specific feature J

k_a, k_b is another pair regarding another feature K

I don't know which is the best way to represent the properties of these lasts values, because for each pair of values (h, j and k) they fit these properties:

h_a < h_b and h_a + epsilon >= h_b

j_a < j_b and j_a + epsilon >= j_b

k_a < k_b and k_a + epsilon >= k_b

I mean, the a value is fewer than b, and moreover the difference between them is not greater than epsilon (epsilon is a fixed value).

I don't know how I should define each sample x. Can I define it as explained above?? There are another better way to represent it??

I also thought in representing x such as:

x (in) M, x={t,m,H,J,K} and For all C, (where C is the set H, J or K) fits that C={C_a,C_b} (C has two values) , C_a < C_b and C_a + epsilon >= C_b

I mean, representing 3 sets (H,J,K) and each one composed by two values (a and b) that fit these properties.

I hope someone could help me.

Best.
