st: matrix dissimilarity

[Alp Eren Yurtseven <aeren.yurtseven@tubitak.gov.tr>]

Dear all,

I want to create a matrix for each sector and year, holding the 
Euclidean distance between all the observations for variables att1 att2 
att3 att4. p and sec denote year and sector respectively. I want to do 
this with a nested loop:

levelsof p,local(y)
levelsof sec,local(s)

foreach p in `y' {
    foreach sec in `s' {
    matrix dissimilarity DE`s'`y'=att1 att2 att3 att4
    }
}

I am not very familiar with loop structures in Stata and not 
surprisingly I get an invalid syntax error. I'd be very glad if you 
could give me some hints to solve this problem. Thanks in advance.

Regards

AEY
