Hi 
can ANY body  help me to programme this formula: 

c[lj]  and  c[l'j]   are  matrix

A[j]^-1  is an invertible diagonal matrix

g[ll']=i[ll'] - sum *#from j=1 to k#*  c[lj]c[l'j]A[j]^-1 

WHERE 

i[ll']= 1/n  sum from i=1 to n  z[il] z[il']

n,k,m  are given.  j=1...k,    l,l'=1...m,  

it s complicate for me ; hope you can help me 
thank you a lot

Well,  I just posted the fourth copy to the list which I apologize  
for. (I meant to delete the response I wrote.)

Re-re-posting an unclear message seems unwise on your part, 'hafida'.  
You are not following the advice in the footer to all messages and you  
are not following the advice in the Positng Guide, so it is no  
surprise that people are not responding.

Read the Posting Guide. From there you should take away lessons:

Learn to use a shift key.
Learn to post your real name and academic or professional affiliation.  
This is a technical mailing list and anonymity will lower people's  
level of willingness to offer advice.
Learn to post R code that constructs a data example.
Learn to provide background.  (.i.e. What are you really trying to do?)
Learn that providing the background regarding why you want to do this  
will reduce the concern that this is just a homework problem.  
(Homework submissions are generally ignored.)

When I suggested that you learn to use the shift key, I was hoping for  
a sparing use of that key, such as at the beginning of sentences. The  
caps-lock key is different than the shift key.

You are also posting to a mailing list whose Posting Guide requests  
that poster include context.
